I understand the diminishing benefits of CR increase as you get into race gas territory but wild CRs will always be linked in my head with wild cams. Nobody with 15:1 compression is running the same cam intake or headers as the guy with 10.5 CR.

Which I guess gets into a dynamic compression discussion which will get in the weeds fast!

For sure the effect a part change has on a specific combo mostly only applies to that specific combination of parts and clearances. At the same time it is always nice to hear about this kind of stuff- especially on a fairly common motor/heads- thanks and I enjoyed the bench racing in the comments too!
