Will SBC 202 heads fit on a Vortec 350?
I have a 1997 Chevy with a Vortec 5.7. My buddy has 202 heads from an old carbuerated 350 and I was wondering if they will work on my truck
The reason I need them is because I plan on a sort of agressive cam. So you would recommend porting and polishing my heads? What would I do about the valves?
They will not. Intake flange angle is different. Aside from that, the older heads won't touch the Vortec heads in terms of flow. Performance loss and BAD idea all around!

sbc heads, what the difference of 196 heads vs vortec heads, in CC and valve sizes, whatever else?
frined rebuilding an 87 350 truck motor for me, yet, he does lie alot.
i tink 4bbl intake bolt pattern are different, he has the old 4bbl intake to put onto this 350, vs buying vortec 4bbl intake that fit properly, but my question is, am i losing anything in swapping to older heads? he has other 400 and 327 heads as well, the motor is a roller cam, 280ish duration under 1/2 lift, so it will have slight lope, which i want. the 87 t/a was 305 tbi, no exhaust systme,radiator,accessories, ct where do i go to buy new throttle cable for carb? what year Distributor to get? if that matter, going to be stock sbc distributor vacumn advance setup. i bought 87 t/a without motor/tranny,exhaust,great paint, body interior. thanks.for input about heads info..my other red 85 t/a is a project as well. is there website to decode the heads, block? thanks for sending that as well.
red t/a is disassembled TPI on a TBI car, no wiring harness found. have computer, no injectors on the fuel rails neither.
Std sbc heads and vortec head intakes are not interchangle. The vortec heads only has 8 intake bolt holes. Std heads has 12. So if vortec heads then you must use an aftermarket intake ment for the vortec style head
The vortec heads makes more power, no questions asked. They are by far the best gen 1 sbc production head made. Easy 40 HP gain over any other stock head
You just need a std mid 70's to early 80's large cap (coil in cap) HEI dizzy with vac advance. Summit racing has a nice aftermarket one for $90 with 50K volt coil, brass terms on cap, etc
