If it is the stock cam with stock stamped rockers, I'd be real tempted to put it together as is.  I've run stock stuff way harder with way worse geometry.  I think this is just me unnecessarily overcomplicating your head gasket job, but then again, with domes, I would like to check everything.

As far as can you change valve seals at home, it depends if you have the necessary tools.  Minimum, you will need a valve spring compressor and every valve needs to come apart.  Then, it depends on the type of seals.  If they are umbrella seals, they just snap into a groove in the valve stem just under the retainer.  If it is they are stem seals, you might need a tool to drive them on.  CompCams and others offer a tool to remove stem seals, but I have never used it.

I am going to say at this point, the valve seals had to be inspected when the machinist reassembled the heads.  If he is comfortable with them, I think I would do as he says and run them.

I'm going to talk to the machinist once more before I waste $100 on gaskets.

But yes this motor has never been taken apart before, stock cam. I don't believe the valve covers have been removed before.

I believe what is in your pics is a composition gasket.  Below is a pic of a steel shim gasket that I pulled out of an '88 3500 454 core.  This steel shim gasket measures about .026".

http://m.harborfreight.com/6-inch-dial-caliper-66541.html is well worth the $20 for quick measurements.

It seems excessive to have .020 cut off your heads, just for a cleanup.  I was just curious what you were doing and not trying to get all up in your mix, but...  I have exhausted all of my resources trying to come up with an idea as to how much volume .020" removed from your combustion chamber.  Without knowing specifics, I think you will be just under a half-point gain if you use the same gasket.  Though the same gasket won't change your quench distance (piston top to head surface), it will tighten up your piston dome to chamber and piston to valve clearances a bit.  You might also have some issues with intake manifold alignment.  The thing that really concerns me is that it could through off your rocker geometry.

It looks like you have some healthy compression judging by your piston domes.  Opening up the quench distance could cause your engine to be more prone to detonation.  In researching the change in chamber volume per amount cut from deck surface, I found that Chevrolet recommends .035" clearance to be the minimum for steel connecting rods.

If your quench distance doesn't become an issue, I might lean more towards restoring the height so that it doesn't throw off your rocker geometry.  If you don't mind me asking, what type/size cam and style rockers are you running?  What RPM are you turning?  You might need to change push rod length.

Again, I didn't mean to overly complicate things.

Happy holidays,

Joe
Joe, I have no clue as to what my cam specifics are. It's a boner stock marine power straight out of 1993. Turns 5100..

I could really use more information from the machine shop. He's well known and highly recommended, just maybe he thinks I know what I'm doing. Him saying valves are fine it was a head gasket problem doesn't provide an answer for the exhaust that's been flowing through my one valve cover.

Is replacing the valve seals at home a doable task?

Thanks

Doesn't complicate anything, I want to make sure it's right when it goes back together.

How deep in the hole are your pistons at TDC?  Try to keep your quench clearance < or = .055

I'll have to check when the weather dries out this weekend. He says my steel shim gasket was likely .038" and I'd be ok using that thickness.

They needed to take .02" off to make them flat..  I think I'd need a thicker gasket than what I had.

I don't own a micrometer yet but I will this weekend.

Any intelligent input on a good head gasket?

What head gasket will you run?
Still researching. I don't know the compressed thickness of the gaskets that are still on the block. plus 10 thousandths that was taken off the heads.

I'll ask the machine shop if they have any recommendations and likely give fel-pro a call and be that guy and pick someone's brain.

Machine chop surfaced the heads and says valves are fine, run it.

These heads haven't ever been off before. Just got back from the machine shop, they showed me where the HG was blown between cylinders. Said my valves are probably fine, but since they're off the guys are doing a valve job and surfacing.

He also told me that the reason the gasket looks off kilter between all the cylinders is so the valves clear the gasket.

Cylinders look good, surprised really. Head gasket looks messed up between the two low cylinders and not great between the others.

Ok the vc that's dirty underneath I'd the side that has 2 cyl with lower compression than the rest. Any guess as to why it's dirty underneath?

I have an Ultra hull that you can have for 16,000 dollars, then you can part out the motor and pump if you like.

Thats down the street from me, but you already know that. Maybe you could se if he wants to do the work. All this pain in the ass is making me not want to do it even more

I think he moved to Norco to be closer to his shop.. according to Facebook. It's the guy in blue.

10mm bolts? Talking about the collector on the back side of the turbo?

No, pedestal bolts.

I should've changed the rubber donuts from up pipes to collector but they were too crusty looking so I said screw it.

I did mine myself, it was a total bitch. I wanted to pull the radio out and cut a hole in the firewall for those 10mm bolts.

I used a good write-up from thedieselstop.com. the best power stroke mechanic in the world is a friend of mine. Matt Stranz at power house diesel in Norco. He lives in Buena Park near la Palma and Magnolia.

Ok the tank i made it sealed & painted & installed. Ill have to fab some brackets so i can use the factory bungee's to secure it in place....the new tank is a bit longer & taller. Also repaired a section of the carb that had broken off & the PO used silicone to "hold" it in place...JB weld to the rescue !

Pics or didn't happen.

Good info here.

62t 701 are good motors but so are the 61x motors. In my opinion they build more torque.

Kawis are more of a bouy chaser and super jets are more for freestyle and they have more torque. It really depends on what you wanna do with it

agreed!  :thumbup:  both of my 701s are 61x.  one single carb, one single dual barrel carb.  single seems snappier (?), dual has more top end.

The ticket motor is a 62t bottom end with the larger intake and a 61x top end with the lower port timing to make the torques.

B pipes wake them up. Mine is stock and I run the shit out of my 701 square several times a week and who knows how many hours it has.. I run cheap oil and gas and it's never missed a beat. I've had two Kawasakis modded out and there was always a project with them. Seems like stock just works for me.

There is virtually no handling difference with a round nose.until you get into 2008 and newer. 1500 will yield a nice square nose. Figure 2k will get you semi clean with 701, B pipe, intake grate and impeller.

I'd be inclined to think that your driveline wouldn't cause a rattle under any bit of load. Thrust bearing get greased often?

I think I remember that team from Whitter narrows track. I used to work at that track and announce there before moving to the High Desert.

My dad built the new tower there. So you know Frosty and I think her name was Theresa Miller...

That was my home track. Jesse and Justin Leal I think lived there.

I used to own Horsemans Bmx in Apple valley. Wonder if you raced then. Both my sons rode there and all the trails and backyards in the high Desert.
I raced there once or twice years ago. Team Pat's 605.
