Going to my cousins shop tomorrow morning for a compression test. Does he need anything out of the ordinary to reach the spark plug holes in our massively deep heads ???

Since the plugs will be out, you might as well put a new set in....

Most the compression testers are two pieces, to fit several different spark plug thread sizes. Usually for the ford heads you have to put on the other fitting. Be sure the tighten the holy hell out of the fitting. If it unscrewes from the tester instead of the fitting unscrewing from the head you will have a bitch of a time getting the fitting out down in that hole. Othere than that the test is easy.

Be sure to tap and shut off the fuel inertia switch.

there is a oring at the bottom of the fitting just make sure it is tight so it wont blow out of the hole, dont over tighten it, it will mess up the o ring.

RD SNAKE, I would have loved to have your results. Lets just say all of my cylinders were lower than your lowest. Leak down test proved my worst fears.
