Me personally I would be looking into a higher compression piston over a big bore kit most of your big bore kits are low compression but im sure there has to be a few companies out there that make some high comp big bore kits just saying if u must go big bore make sure u go high comp or u ain't gonna notice much difference just my 2 cents
