Ok so i fried my piston and ordered the 143cc bigbore kit with race head as well. My dcr cam wont work with this head. Cam is new and still wrapped up! Im wanting $250 and you pay shipping. Cell is 832-857-5902 call or text me any time! I wish i couldve dyno'd it with my yoshimura exhaust and chimera intake and pcv5 i made 10hp so im sure with this cam id be at 12whp!
