so tonight i just put a cp piston in 13.75/1 and i also have a uni filter with hmf slip-on so if anyone has a good map for that id apriciate it. and i was an idiot and broke a bolt on the head for the header! i just left if with one on there for now. will it be ok with just one bolt holding the header on or do i need to get a whole new head? what are my options?
