B21F: 'A' cam + 10.5:1 OR 'K' cam + 9.3:1 200 1979

Hello all, I need suggestions.

I run a B21F with a K cam. After polishing the head's combustion chambers, I was planning to raise the compression ratio from my present 9.3:1 to 10.5:1. But shaving the head while still keeping the K would make the B21F very much "interference".

Would I generally be happier by continuing to use the K at 9.3:1 comp. ratio...or by raising the comp.ratio to 10.5:1 and installing an A cam?

I am all ears... Thanks!
