That's the point - more static cr needs more overlap to avoid detonation and vice versa.

If you go with a motivation cam you need some more static cr.

Port / valve seat design helps you to gain flow and velocity - a good header concept too.

Do not forget about squish band design also.

Bring it together and it runs as it should.

Best reg.
