The simple answer is probably ... but we don't exactly KNOW what's in a rebuilt motor nor in any given motor unless we KNOW that motor's specifics. That's why I wrote "about" ... and suggested doing what ifs with a comp calculator.
STOCK OE L48 retrofitted w/ 64cc chambers & felpro 1094 gasket make about 9.5:1 scr.

I understand the intake bolt-holes with vortec heads & intakes are 'vertical', or 'straight-down', unlike traditional SBC intakes and heads, which go 'straight-INTO' the cylinder head:
if this is true, and you'd take a big-whack off the vortec head, is it possible the bolt-holes won't line-up properly, because even-if you'd face-off the side-flanges of the intake (to allow the ports to match-up properly ), the bolt-hole center-lines still won't be in-line with each-other.....
is this reason-for-concern with vortec-style heads, or am I as F'd-up as a football-bat?

I'm not knowledgeable about vortec-heads, but I want to ask this question of 'jackson', as he might know.....
