If it is a stock motor, I'd bump it down to 40hp. replace the valves and valve springs if you want to go higher.

I spit shims on a 40 shot that was tuned perfectly. I also had it set up as progressive with a window switch set from 6k-10k. No way it went into the rev limiter. It now has 65# APE springs and Gen 1 valves. Been spraying it with 50 with no issues since the upgrade.
