You should report the conclusion of your compression test to close out this thread.
I recently had a situation with having took the timing belt off and cam was 180degree off on a 4 cylinder 2002 accord. I was concerned with valve interference if I turned one without the other, and didn’t have time to remove valve components. What I ended up doing is as follows:
– by hand, turn crank 1/4 turn (if any binding, stop and don’t force it)
– by hand, turn cam 1/8 turn. (Expect some valve spring back, but don’t force it if it binds)
Repeat above steps until you achieve a total of 1/2 turn of the cam.
After reassembly and compression test, my lowest reading was ~190psi, thus no valve damage with what I did.
Hope this helps.
