looking for a set of square port heads for bb chevy for a friend...........oval ports if i have to, and then a performer manifold to match the oval ports...get with me
-
I have a set of ovals , they have been maged from the macine shop and are ready to be reassembled.
-
I've got a set of bare 990's (?) that may need to be worked over.
-
my bad... I just read that it was for ovals.
Anyhow, for beerjet: 14097088
-
If the heads are for a jet boat, you'd be better off with the large oval port heads. From what I've been told by several jet boat pros, they're much better for mid-range RPM than the rec port heads.

How much $$$?

Sure, as long as you throw in a Rooster Booster. ::)

I honestly don't know what their value is... I believe the seats can use a little cleanup, and they aren't warped.
I'd would be open to trade for a droop / droop snoot -I've been wanting to see what, if anything, it would do for my ride. Open to trade for other jet performance parts????

I think I might have found you a droop snoot, I'm working on it...

Are these heads for a jet boat? According to my BBC Book (How To Build Max Performance Chevy Rat Motors by Ed Staffel, published by SA Designs) rec port heads are more for a motor that will be spinning 7000+ RPMs. For a jet boat large oval port heads are your best bet IMHO. Just my $0.02.

These were on my jet boat. I read somewhere on the 'net that these were used from the mid 90's and later for Marine 454/502 HO. They were stock on my boat -never removed or worked on. I burned up some valves the summer prior and... long story short, I went with a new a$$ebled set and these have been in my garage since (bare). They have been magnafluxed and from what I was told these can be worked on -I didn't have to time to wait, hence the new set. I don't have the know-how to es'plain much more other than that these are heavy ass paperweights that bend wood shelves when stored too long.
If you're local you are more than welcome to take a look. I'd rather hook someone up on the boards for a reasonable price than make a few bucks on a random shmuck. Karma. I'd be down to trade for any jet boat goodies. A droop/snoot + $? or anything to make me as cool as you guys... ::)
-
what size valves are the heads set up for?..open or closed chamber.....and yes its for a jet boat, duh...
***another question...can a square port manifold "work" on oval heads...tring to save some $$$$ here!!

You can use a rect/sq port intake on an oval head as long as you use rect/sq port intake manifold gaskets.
I have a set of 049's but I wouldn't part with them until after I've got a set of rect port heads. :-\
Legal Chemistry, PM sent.
I phoned the local guru's and... uhg... must have thought I was completely stupid, told me both 049's and 990's cores are worth $100 - $200. NOT. Someone told me 049 cores are worth $200 - $250 (ea) and 990's $250 - $350 (ea). ???
-
Be careful if you go 990's because they have been discontinued.

Haven't the 049's been discontinued for a long time as well? Weren't the 990's replaced by the identical 880's which are put on marine crate engines? ???
-
I don't know about the 049's. The only reason I know about the 990's is because I ruined one on my last motor, and when I went to buy 1, everyone laugphed at me.
I called scoogin dickey, I called every machine shop in utah ect. BTW not sure about the 880's.

Here's some cut/paste info from a quick search:
14097088 1989-94 502 Open GEN V, 118.0cc, IP 325cc, replacement
14097088...91-up...rect...OPEN...Gen.V 454/502 HO, 118cc chamber
14097088 Iron Cast Open 118cc I: 2.19" E: 1.88" 325cc Rect. Square use with Gen V big-block engine P/N 24502618-20 "BARE"
I thought these were still used on crate engines? Hotrod, was the guy you talked to looking to buy heads for that price -that would explain $100.
c'mon, anything to throw on the table. My boat barge want to get movin' on up the slow river this year. ;D

Sounds like the 880's are basically the same as 990's however the 880's were on Gen V engines whereas 990's were on Gen IV, I don't know if they're interchangeable. ??? Yes, he said he'd have to see the heads but he said he'd probably give $100 a piece for cores. I will swap you for the droop on my boat but I'm sure you can find a better deal out there. ;) I've got pretty decent heads already and I am more interested in getting the rotating assembly that I am going to need.

'049's seem to be the most popular jet boat head I have seen run. Lots of jet boaters run them and swear by them. Chris Straub will even tell you that for a jet boat '049's are capable of some serious power.
-
what a bout some heads like these #290 101 cc chambers oval to rect ports . I have built these heads
for jet's was going to use on my flatbottom but going to bbf, Have built lots of these heads for jet's they are good

-

Not sure I understand, but are you saying you changed those to rect port? It sure looks like it. I had those heads on my last engine, real good for making compression. I was told the only thing "wrong" with those heads is that they couldn't breathe well enough, it sure looks like you took care of that problem! What do you mean by no "stones on your heads"? How much $$$?
-
It depends on what some wants full port & polish or mild port pocket cut , I dont
use stone on my heads they are cut with a mill using tool serdi witch is a blade cutter it
has all the angles ground in it ,I tried to post picture of it can only get one picture at time to post

Resize your pics so they are smaller and that shouldent be a problem.
