Anyways Tom if you get this soon enough i want to ask you a few questions regarding my gt40p heads that i've got. First allow me to tell you my plan, Daily Street Driven Fox Mustang, Stock Cam, Explorer intake and now the heads. I want to know what i need to get to complete these heads. I want 1.7 roller rockers but i dont know what kind and where to get these also the ones that will work with my heads(cheap/good quality kind). Valve Springs, where and what kind should i get(cheap/good quality). The heads will be going to machine shop to get cleaned up and im still undecided to know how much i should mill them. I'm not going to supercharge my car at all, just pure stock N/A, and i run 91 octane ALWAYS(cant find 93 octane where i live). Help me out. Also for shits n gigs what do you think my rwhp would be once im done with a tune.
