[Chevelle-list] Aluminum Heads..

[Dale]

Must have missed the ZZ350 engine, I've seen ads for a ZZ350 but that's just
the short block. I know the ZZ4 is a 350cid, 355hp and came with aluminum
heads, is that what you're referring to?

 

Here's a good article on the Vortec heads -
http://www.chevyhiperformance.com/howto/97458/

To quote a couple of sentences specific to your question, "The Vortec
requires a special Vortec intake manifold available from both GM Performance
Parts and Edelbrock."  And, "The most important detail is that the Vortec
uses an eight-bolt intake manifold pattern that is different from the
standard 12-bolt pattern."  Naturally, center-bolt valve covers must be used
as well.

They are off a ZZ350 Crate Motor....

Just wondering if they are compatible to my 327...I don't want to tear
things apart to find they don't work..
