The heads are a pair of Edelbrock race heads, should be 58cc chambers. I don’t own them and there is a pair for sale. I wanted to get some opinions before buying them and finding out they are too much for my intentions. My cam should be good for them but the question is it too much for a warmed up street cruiser. Trans is a 42rh and I got about a 2500 stall converter. Car is an ebony, probably use 3.55 rear gear.
