A little help with heads....

[Zoerb]

Ok, I have 3 sets of heads, all different castings, and I want to figure out what would be worth it to use. first the engine is a 350 4 bolt, cam will be a little more than stock (havent selected one yet), edelbrock performer intake and 1406 carb. this is going in a 72 c10 with a th350 and 3.08 posi.

Basicly all that being said, heres the cast numbers:

3932441
3998993 (made in mexico)
333882

yes I know everyones view on vortec heads and aftermarket heads. I have a VERY small budget for this build, and I need to use what I have. the truck is not going to be a power house, it will be a summertime daily driver.

Thanks for all your help in advance!!
