valve spring height question

926 spring installed at 1.75-1.775 gives 120-130 on seat and ~305-315 over the nose.

Stock rocker? If so they aren't going to give full theoretical lift so the true over the nose pressure will be lower

No coil bind issues and a better spring rate than the 911 spring.

I get the sense this is an ask the question and want a specific answer that fits a predetermined choice because it's what's in hand.

Make sure the spring fits firmly in the cups/pads, if not, you need to run a locator for best results.
