Alright heres the deal: I can not keep a stock 22r togather at all (blown 2 in 3months) so I figure I need to build one up that can sustain a rev without coming apart. I am thinking a 22r that is bored .40 over with forged rods and dome top pistons aught to be plenty substantial. For the top end I plan on a ported and polished head running oversized valves (how big?) with HD springs (how burly?) I know I am gonna need some sort of rocker work but I dont know what. And for a cam I want one that will make power from 1k rpms all the way up to 6.5k rpms.

Also is their any way to put a rev limiter on one of these pigs?
