86 vette heads, aluminum

[modulistic]

having trouble finding out much about them. a guy wants to sell me some for 275 dollars.

I want to use them on a 1968 327ci small block.

I guess they will bolt up to the block, but im not so sure about the intake, exhaust.

are they even worth a shit?

275 isnt a bad price. They are identical to the cast iron version. 58cc combustion chamber with a 163cc intake runner. As cast they arent very good. Some port work would do wonders for them. Why not buy you a set of vortech heads? All you gotta do is buy a vortech intake.

exhaust is d-shaped ports on them; you run some chance of blocking the port with the "wrong" headers / gasket.

The intake is standard small block; all bolt holes are at the same angle.

They're 1980s technology. Vortech / Fast Burn / Etec heads are 1990s tech.
