Cylinder Heads Interchange Question

[1964_442]

excuse my dumb question
Can I use heads from the '60s & '70s engines on my '95 Block? I've read on catalogs something like: < 86 and, from 87 up
whats the difference?



its a SBC 350

yes, but why? the old heads were good for their day but are outclassed now.
IMO get a set of vortecs, they're cheap and make good power.
edit, i'm assuming you have a gen1 block, right?

87 and newer have a different intake manifold bolt pattern. It can be adapted, but they aren't a direct bolt on.
Of course if we are talking about LT1, or LSx heads those are completely different. The Vortec head needs a specific intake manifold

[1964_442]

so the difference its just the intake manifold?

[mongoose]

pretty much... and valve covers..

the vortec intake only have 8 bolts... where as 87 and up still ahve 12 but they're at a little different angle.

and i'll sell you my edelbrock performer vortec intake

[1964_442]

first I need a set of vortec heads.. anyone selling ?

[megaladon6]

i can probably get you a used set. i'll ask my buddy.
just in case you don't know, vortecs will only handle about .480-.490 lift. this is easily corrected by a machine shop and i think it only costs about $50
