When to rebuild topend?

[hotrodbanshee]

On my last rebuild I started out with 185psi in each cylinder. How much psi drop should there be before doing another topend rebuild?

i doubt that 20cc domes would actually get you 185 psi.

if your compression was actually 185, then i would probably do it when you get down to like 165 psi, or even if the guage isnt accurate if it reads 20 psi lower than before i would say thats good time to rebuild.
