Continuing: So, getting the rings on, and the piston in the cylinder is a pain in the ass. Or, in the finger, as the case may be. I am using a ring compressor with a key to tighten the loop around the piston. Even with that, it is really tough! (Tool pictured in upper right of this photo.) First one got in OK after a little manual work to get the top ring in. The second one... not so much. I managed to break the (brand new! $16!) oil scraper ring because the ring compressor was not closed enough, and I tapped the piston too hard. I almost think that just doing it all slowly by hand would have been better. Oh, well. New part ordered. At least ONE of them is done. So, my next step was to put the cylinders back together with the heads. The heads were perfectly clean, but the cylinder side needed to be cleaned up. The head & base gaskets left quite a residue, and was nearly impossible to get off without considerable effort. Final solution was to use a "Roloc Bristle Disc" carefully: (Thanks to @jdaniele for his help cleaning this up!) PRO TIP!: Now is an excellent time to do a valve adjustment! With the head removed, it's easy as hell to install the cams and simply rotate them away from the buckets. No timing == incredibly easy and fast to do. Which is good, because when you clean up the head, all your adjustments need to be re-done. Now, it is time to install the head gasket. Make sure you still have the dowels installed to hoe the gasket in place!: Before reassembly, I carefully swabbed all mating surfaces with brake cleaner to make sure there was no oil or other contaminant, anywhere. Place the head gasket on the head. It only fits on one way: Interesting note!: The head gasket blocks some of the passageways! The coolant passages on the intake side are blocked except for two round openings, and the two smaller passages on the sides are blocked entirely. This seemed strange to me, but the old gasket was the same way. Fit everything together: Don't forget the loctite #243!: ...Then torque down. It's a two-step torque process. First, all bolts to 18 Nm. Then, go around again to 23 Nm. All done!: So, I'm waiting on a couple more parts which should come tomorrow. With any luck, I'll be able to update this thread again in a few days.
