No worries - it ain't gonna reduce friction, but the extra lift/duraton is worth thinking about. It's a pretty minor improvement if any - again, I'd see elsewhere but it's your dime
When moving from 1.5 - 1.6:
- Multiply 1.5 lift by 1.067
- Every .1 increase in ratio increases duration by ~2 degrees
- Be SURE your springs are up to it; check for coil bind and rocker bind carefully.
- No value unless the heads will flow to that level of lift.
