Ive got a stock gpz750 with a blown head gasket...after researching a fix, I've decided that I might as well do some mods. the bike already has a 4to1 header and a dynojet staGE 3 KIT WITH POD FILTERS. It has 12k on motor so I'd like to have a fresh rebuild for summer. So heres what I'm thinking, i could use some advice as to get the most bang for my buck....#1 wiseco 810 kit, it has been suggested that bigger valves will help but a better cam will be needed, where do i get cam,,,and are tgere hi pro valves to suit. the bike has a supertrapp pipe and I'd like to upgrade that also, so hit me with it gurus... where do i go now
