Does anyone know the cylinder head volume on the Pre-Vortec 350 heads, 87-95? Were they 56cc, 60cc, 64cc or 72cc? I can't find any info on this. I want to put Aluminum heads on my 1996 350 and don't want to loose compression.

Hey Rick, There is a book by Dennis Moore about "Small Block Chevy Marine Performance". According to Dennis there are two types of heads for your engine. If you are consirering of messing with your motor this book is a must. I got mine from Amazon in just a couple of days. Good Luck and keep us posted.

Probably 76cc, but you should get the casting numbers and look 'em up to be sure. The Mortec website (http://www.mortec.com/castnum.htm) has a listing of cylinder head casting numbers and with combustion chamber volumes.
