Hello everyone, I’m thinking about some power mods for my 350 tbi it’s in a 91 c1500. I heard a lot about vortec heads. Just need some guidance on which ones to look for and what not to. Like 8 bolt or 12 bolt, I think something like that. Other than that what are some other mods I can do that doesn’t break the bank TOO much.

At the moment I have pretty much a straight pipe 3 inch. Stock headers tho. But that’s it for now. Just wanna see what everyone suggests about power mods.
