150psi when warm is a good ballpark. Not sure what the 'book' figure is though. So long as they're all pretty similar you shouldn't have much to worry about.

160/170 for a HC engine in good condition....

Be sure to do it hot engine/all plugs out/throttle held open - brick on pedal is ideal......but remove it before you try to start the engine again.....

You won't get the best figures from a newly rebuilt engine, the rings need some time to bed in.

500 miles and they will be as good as they ever will be........ PM me to discuss if you like Dale.
