School me on what heads to buy..GM SBC

[93EGY8]

Well guys i recently picked up a 350 for my camaro, but its not the ideal motor that i wanted. Its a 5.7L 350C.I. small block, it came out of an 88-94 chevy pickup, its an HD block with a 4 bolt main, so the bottom end is pretty strong. Its a non roller motor though.. which i didnt like. After some research i found that the motor makes 300 ft/lbs tq, and 225-255 hp. The problem with these motors is the heads hold them back from the factory. I already have a Barry Grant Demon 750 double pumper that i bought from my uncle, and an Edelbrock high rise intake manifold, I just have absolutley no clue what heads to put on this thing.. i dont have the money for aluminum just yet, so im trying to stick with a set of decent flowing factory cast heads.

to sum it up.. heres my questions..
1.) I would like to put a set of heads on from a 70-73 z28 or nova ss, obviously a pre emissions standard car. is this possible on a non roller motor?

2.) Any of u Fbody guys running a similiar setup??

3.) am i going to run into problems putting a cam and heads on this because of it being a non roller? *obviously meaning roller cam, right now mine is flat tappet.

sorry for the huge post, but i am totally lost right now.. guess i was in the honda/nissan game to long and forgot my roots lol.. thanks ahead of time!
