Stock cam?

Oil consumption??

The reason I ask is if there's high oil consumption it will make that motor detonate at high rpm.

The stock cam, and valvesprings, is a huge limiter to rpms and top end power.

I'd doublecheck that total timing and then consider a cam/valvespring swap.

The carb tuning suggestion is a great low-buck idea to try right away. It could help with the detonation, maybe.
