The 455 heads have 76 cc's not totally sure on the casting #'s at the moment. Well this is starting to seem like I should just use the stock head's for now since i'm running on a budget. Found a set of old 350 #5 heads for 6 bills with shipping, said that they have been rebuilt any insite?. Any advise on reusing the stock heads? They were doing great no smoke or valve chatter.
