Been on the case with the engine rebuild for the last couple of days. Having cleaned the outside of the head casting i turned my attention to the working parts, clean them down and check condition etc. The timing-lock backing plate on the pulley has come free for starters, so that came straight off, will fit the one off the other head. Disassembled the rest of it and got heavy with the degreaser,:

...cleaned up the mating faces,:

...and put it all back together:

Rockers, lifters and cam races were all super-clean, was a tiny bit of surface rust on a couple of the cams, but that cleaned up in seconds with some 1200 grit. Will be building a better head for it fairly soon, so it'll be fine for now. Mating faces were cleaned with a razor blade then another light application of 1200 grit, sneezed hard at one point with the razor, but thankfully only nicked the outer edge of the mating face. Head is now fully assembled, excepting injectors, and ready to go back on. Turned my attention to the block, cleaned up all the rust with jenolite and gave it all a heavy keying, then got busy with the VHT spray paint:

Unfortunately it seems the paint i bought is a load of shit and pretty much rubs off after 24 hours drying time, so will be picking up a tin of engine enamel and doing it the old-school way. Next job was the mating faces on the block:

Since then i've honed the bores, washed the block down thoroughly and done a lot of mincing about on ebay looking at bigger turbos (already, i know...
). No more piccies for a week as the missus has taken the usb cable on holiday with her, but progress will continue at a similar pace, engine should be finished in the next couple of days and will be moving on the fabrication...
