    Thanks for the post - this was educational since I also just bought a sitting '86. We'll see what we find.

    Decided to play the ebay lottery. I picked up a used crankcase, pistons & connecting rods. Supposedly 30k miles on the engine.
    Some minor pitting on front cylinder walls (ie. likely common for this model), back cylinders #1 & #3 look good:

    Oooh, tempting.
    Was it you or someone else who posted last year about replacement orings for oil lines & cooling tubes from McMaster Carr ?

    Wasn't me, but I source my own orings for quite a few things, especially carbs. Not hard to grab some dimensions and find what you need (in Viton).

    Fired off the parts cannon this weekend, started with online order at oringsandmore. Haven't ordered pistons rings yet.
    I went searching for my honing tool which I haven't used in 10+ years. I found it under pile of basement crap, one arm bent and stone smashed to bits. I guess this is my chance to try out one of those ball hone tools.

    Cleaning the front head today.
    #2 cylinder looks pretty good

    However #4 combustion dome has good amount of corrosion.

    squirrelman earlier commented maybe a blown head gasket had caused the rust. I checked the head gasket for signs of leakage but didn't see anything.

    Is this head past recovery ?
    Plan B is swap in a spare 87 head.

    Maybe carbon disguised as rust... can't really tell from the pic. Try chipping it off, nothing to lose. Maybe on both while it's apart, pull the valves and lap them?
