As I continue to hibernate here in Ohio I've had time to search the local craigslist, and one of the more interesting things are vortec heads. Just to confirm before I get myself into trouble, I can run those with my same 350 SBC headers? Do I really need to get a larger carb if I'm running a 650 edelbrock and their vortec manifold? Think I'll get noticeably more power out of a 8.5:1 compression with mild cam? For around $500 for the used assembled heads/intake it seems alright, and leaves some potential to build a 383 long block to put that on in the future. Apologies for the rambling! So do you think vortecs are worth fooling with after you figure in all the stuff you need and have to do to make them work? Or am I better off getting some aluminum heads and spending the extra money? thanks!
