Valve clearance cuts on a 7-to-1 comp. engine..hummmm...???

I've done relief cuts on 10.5-to-1 comp. & up engines before, but not on such low comp. engines. Although, my experience has only been with V8's.

So are our 930's different???? Are the pistons chasing the valves that closely?

Curious minds want to know!
