Trying to think of some easy and somewhat cheaper mods I can do on my 1991 camaro rs 3.1v6. I heard heads are somewhat restrictive, what heads would help? What else can I do to get rid of some restriction? Any cheap mods that will help me get some more pick up? And also I'm thinking about getting a better cam. Any good options for a stock 3.1 that will add some power and pep? It is a daily driver at the moment and I hope to keep it that way. Thanks for any help guys
