i put a SMALL dab of silicone around the water passages for my intake manifold gasket. they usually dont require it if you're using new parts, but older stuff has some pitting usually around the passages and its just a little bit of security against leaks.

what motor? when i assemble heads i put thread lube onto the bolts and i use permatex sealant on the ones that go into water passages. thread lube helps with getting a proper torque rating on the bolts. before all of that ill also run a thread chaser down just to clean up the threads and remove any old lube/gunk.X2 good answer right here!

Will this work for the ones on the water passages? This is what my machine guy said to use.. and what do you mean around the intake water passages, got pics?

i could recommend NOT to use that. pipe thread is a compression fitting... if you look at a pipe it starts small and is angled. as you tighten it, the 2 pieces wedge together and make a seal...

Though I would use what dat1dsm recommended. Also the ARP is good stuff but research the bolt/stud with Arp vs. oil or any substitute as sometimes it is 2 different torques. You can get both on Amazon- Got a prime acct and get stuff in 2 days and Sat. Well worth it- Plus Movies!! ;)

Not to high jack, but the permatex is rated for that as well- No experience with it though.What did I recommend 240?

Sorry meant to say what Ka0tic recommended-
That being said I've seen motors with nothing but Ultra Black, Ultra Grey and as well and they sealed fine, used it on all my triumph race motors. You have many options and they will work-

Don't use anything that says "thread sealer" on the tube. Use ultra black...sparingly.Got pic of it?

Fel-Pro MS 90240Thanks Ka0tyk. Do I wanna block off the square ports?

put in head bolts torqued to 70 ft-lbs in three steps of 40, 55, and 70 ft-lbs in the pattern below (so do 1-16 at 40, then 1-16 at 55, then 1-16 at 70):

bingo. a small dab of high temp RTV/silicone around the water passages. lube/oil on the head bolt threads and thread sealer on the bolts that go into the water passages.I put the heads already the other day. I put permatex2 on all head bolts cus they all seemed to go thru water. On intake tho, I think only 2 thread all way thru. On those little metal restrictors, leave the little holes open too?

the squares are little metal restrictor inserts. your intake has the crossover tube in it. if you use a gasket with it blocked off, eventually the water will penetrate it. the crossover tube is to warm the intake air when cold to help with keeping a constant air intake temp for smog and smooth idle when cold in a car, and also to cool the intake from the hot oil splashing on the intake manifold from the cam whirling around. honestly with the oval port heads and intake you're not exactly going to notice the difference with it open or not. MOST aftermarket intake manifolds are gonna have it blocked off.
Not to be picky but water does not flow through the crossover. Exhaust gasses flow through there. Yes it heats the carb base to help cold start, but mostly it's an EGR port for emissions, which boats don't have, so yes it should be blocked off.
OP, the cardboard intake gaskets will work fine. Make sure your surfaces are clean, and put a very light coat of silicone around your water ports on each end. Throw away the end gaskets and run a bead of silicone on each end. Let your silicone sit to "air" about 5 minutes before you set your intake on it. Tighten from the center out and don't over tighten the bolts. Torque is 25 ftlbs . I've added a link from Edelbrock that shows the sequence at the bottom. Good luck.

Thanks for the help guys. I'll make sure it's Clean and torqued right
