Vortec Heads
I acquired a set of 12558062 vortec heads that I'm considering installing on the 71 350 that I have in my c3. When I rebuilt the 350 I installed flat tops and was wondering with these heads what kind of compression ratio I'd be looking at by using these heads. Nothing exact just ball park, Thanks Larry

My 77, with Vortec heads, has an Edelbrock Air Gap manifold, 3/4 thick adapter, Qjet and a drop base air cleaner with 3 inch element under the stock hood - just barely.

Keep in ind the Vortec heads only allow for .450 lift cam(approx.). Comp Cams has a tool you can use on your drill motor and modify them at home if you want to use a high lift cam.
