Time for a new top end

[czrider263]

I had a chance to buy a sparks racing pro head and top end used by john natlie and decided to get it. So today i tore my old top end apart. It has a wiesco 13:1, porting, and sparks cam. The cylinder was replated to fit the piston perfect. With this top end i hit 45hp in 5th gear on the dyno. I don't know what i will do with my old top end. Im picking up the sparks top end on monday. Here are some pics of my old top end.
