some compression testing advice

[Dutie]

Wanna do my first compression test. Have a pretty good idea but would like to first run it by some more experienced minds. I am thinking let it warm up some, plugs out, key off, engage starter from under hood and check gauge. The car is a 31 deluxe roadster and is my avatar pic. The engine is stock with a high compression head, maybe a comp. test will give me an idea of how high. Motor has been redone in 97 and has about 2500 mi. since a full restoration. Had this car about ten years and have it running great thanks to a lot of members who have helped out from timing to corn head grease. I am an older fella but a good learner.

thanks again dutie
