540alex,

An engine with enough miles to have low compression could also have less than specified closed and/or open spring loads on one or more valve springs. Please don't misread this. I'm not saying weak springs are the case of your low compression. I am saying that the miles that would cause your worn seats would probably cause some springs to be below spec loads. With your meticulous cleaning it would be a shame to reinstall even one weak spring. Even worse to not check them at all

I realize its easy to sit here and suggest things for you to do but I would be remiss to know this and not mention it.
