Do the compression tests first, dry and wet with a warm engine. Someone here mentioned using a drinking straw to add oil to the cylinders: Insert straw into oil bottle to a depth of 2 inches, place finger over top end of straw, move to spark plug hole, remove finger. No mess and 2 inches is about a tablespoon, just perfect.

I would expect compression to be around 150 dry and 175 wet, even though the NA specs are around 200 for a new engine. The rings will wear for at least the first 100K miles.

Removing the head and replacing the stem seals (all 20 of them) is not a lot of fun. Removing the engine is even less fun.
