Trying to figure out my calculations and I was wondering if a corrected compression of 9:44/1 and a Cold Cranking Compression of 192.6 are OK in my 110" with compression releases. Also, the majority of the time I can only find 91 Octane.
Thanks

You should be fine.

I agree the numbers are in line. But I would add that a engine that is untuned will not run correctly and even with correct numbers for given fuel octane will not help you. Smaller cams with short duration tend to be more picky than larger cams with a increase in overlap for ign ping.

Maybe some specs on the build ?

Wood 7H cam, 10.25/1  compression, vance hines pro pipe chrome, cometic .030 hg.

That should work just fine tuned correctly

Thanks, do you think this will be a hard tune? I am concerned as there are limited tuners in my vicinity.

Nothing exotic about the build, and the tune should be straightforward.
