Definitely seems like who ever did the rebuild for previous owner didn't know what they where doing or tried to skip some steps. I borrowed a granite surface plate at my workplace over the weekend to sand the head flat since it had some warping. I'm planning on reassembling and testing the compression in the next couple days when the head gaskets come in the mail. Really need this thing running before the snow storms hit soon.
My thoughts are as long as it has good compression and I've flush all the metal out as best as I could and I've cleaned out all the carbon buildup It shouldn't get too much worse before spring.
How should I proceed when I find a machine shop that will do a rebore? I have a lead on one that may do it. Do I bring the engine to them broken apart so they can measure the cylinder before I buy the kit of parts? I know the next bore would be 20 over but I dont know how to measure if I need an oversize crank.
