If you have gauge with bleed-valve far away from cylinders, like near gauge, you'll want to see 120-150psi cold/wet with usual 10% variation between cylinders max.
If your gauge has bleed-valve near spark-plug, you'll want 170-190psi.
Even when raced these engines don't wear out very quickly. You're more likely to have worn clutches and suspension. Check valve-clearances. Valve-stem seals seem to wear out quicker when raced in hot climates.
