Getting ready to pull heads

[redmt]

I would run a leak down test first. High compression could be a sign of excess oil on the cylinder walls. It's not uncommon to see oil scraper rings installed incorrectly. If everything on the lower end checks then I would look at the valve seals and the type. You can check for excessive guide wear without pulling the heads.
If your still looking for a top of the line machine shop with real world prices go see Bobby Gaines at Bell and Gaines in Modesto. I've been using him longer than I can remember.
I do have a leak down tester you could borrow.

1. Ive got one of those motor puller plates that i will bolt down and seal with some rubber to the intake with the carb off,

2. pop the valve covers and release all the intake valve rockers closing all the intake valves, compression was good so i assume these seal,

3. Put a vacuum pump on my brake vac line, with the PCV line plugged (both come off the manifold just below the carb (trick flow R single plane).

Apply vacuum and listen/observe...any really leaky guides should make noise? Should also check for sealed intake manifold gaskets?

Anybody ever tried this or something similar? I would think it will determine if there is a problem topside or with the rings?

I just hate the idea of pulling the engine for logistical/working space/help reasons...Heads no problem.
