Re: 59A low compression #4 cyl
I can completely understand the desire to not end up with two flatheads in the machine shop at the same time. I think for the time being, you should clean up the surfaces and re-install the head with a new gasket. Then, as "marko39" suggests, do a leak down test to find out where the problem is. Depending on what you find, I would button it back up and fire it up. You didn't say how long it had been sitting, but things can get gummed up over time. If the engine doesn't make any funny noises and has good oil pressure, using it may just loosen up anything that may be sticking. Proceed step by step, and there is a pretty good chance that you will end up with a good runner. (Don't forget the MMO and maybe some SeaFoam.)
