Well im building my engine and i almost have enough money for some aluminum heads. But i dont know what size to go with? i know the valves are going to be 2.02"/1.60". With a 64cc Combustion Chambers. So should i put some 190cc intake or some 210cc intake on.

The engine is a 350 .o30 over 355 10.1 comp w/ 64cc heads.
Stock rods.
Stock crank.
Cam is a 480/480 lift.Hydraulic Lifters
Heads are going to have 1.6 roller rockers.
Dont know about intake yet.
th350 with a 3300 stall. auto
Tell me what you think of the set up?
Thanks

Cam is to small on the lift. For the heads 180, 190, 195 or 200cc intake runners will do the trick. I would not go over 200cc on a built 355.

what size cam should i use then cuz with the i mesed up the cam is a 512/512 lift

Looks like the cam is the same (the old 280 Magnum it looks like); you just have 1.6 rockers.

Try to get chambers smaller than 64cc, if you don't have pinging problems now. With aluminum heads you need close to a full point higher CR to get the same cyl pressure (power output) as iron heads.

So your saying if i want 10.1 CR i would have to go with a 62cc or a 60cc to get 10.1 CR. Im just dont know what size heads i should go with to gewt some good hp.

Nice set up.. But I would go with 4valve after market aluminum heads if you can get the money. It would make a sweet *** engine.

327???

I think a 195cc intake runner is perfect for a street/strip 350. My preferance would be Trickflow or AFR.

Bad idea. It's seriously NOT worth the hassle, not to mention the MASSIVE price of a set of such heads.
