Cylinderhead for "Reserve"

I had a black Z1R cylinder head in storage, which I took to the paint stripper the other day and got back today. The paint is almost completely gone. There are just a few small inner corners, but I can get those clean with a small rotating wire brush. I've already lapped the valves and seats. So I have a relatively good cylinder head in reserve. ( We all know: To have it is much better than to need it!)

(( I´ve given the plug threads a little kind of "cleaning cut" with the correct tap M14 x 1,25, so final job is to put on new valvestem seals, springs and valves ))

Just thinking..Why not paint the head black again? Wasn't all Z1R motors painted black.

Sure, all Z1R / D1 / D2 engines were black,... but I only have 2 Z1000 with their bare aluminum engines , ...and for these the cylinder head should be (in an emergency maybe..or if i will find an engine without head...?)

Joe, spare engine you say, do i have a deal for You! KZ1000 "spare" engine on a rolling dolly of crappy/cracked KZ900 frame. Just have Jeeves heat-up the hot air balloon and fly on over to pick-it-up. See you in a month, haha.

I could do something with that Clay but at $1500 for shipping !!!

Clay, your offer is too good to be true, thanks a lot,..but all my useable ballons are today out of function, i am too sorry  ...

( But it can be a nice project for a specialist like yourself ??? 

Wookie, perhaps no one would notice as a "carry on" for flight, stuff it in the overhead compartment, hehe. Sorry to hear Joe of Your hot air balloon issues, like a pin-cushion or just out of propane?   

Ha, You know Clay, ..Whenever you need the balloons, they don't work...it´s a miracle...hmmm

This morn, i´ve complete the head with the fresh in-lapped valves + springs,..the valve guides have been wery well,..no action was necessary for them, thats alot of luck, and of course, it saves a few bucks also about..

I Love the spring compressor, maybe some left-over tool for the Lancia/Triumph/Peugeot/Fiat etc..Ha. I'd made my similar version out of a simple c-clamp years ago.  

I´ve build, or better say, "customized" this clamp for more than 35 years ago, and it still works on most of my overhauled heads good enough,..soo good, that i´ve never had the need for another one...
( On my Chevy heads, few yeas ago also, i don´t need the "lenght-adaptor), (silver part on foto), i used that bare,..the slot has been absolue ok for the valve stems...)

We're birds of the same feather then. I've been modifying crap for years too!  . A long 3/8 socket works too, just have to cut a bit out of it to access the keepers, haha 

This morning, I quickly made the 8 guide bushings for the camshaft bearings:
(The guy I bought the head from lost all 16 screws and the 8 bushings...).

(When I make such relatively thin-walled and small bushings, I always convert my lathe to a collet chuck to ensure that the roundness or dimensional accuracy of the bushings is not compromised by any "squashing" or compression!)

I used 8x1 mm precision steel tubing for this, which has exactly the same dimensions as the original bushings. It's important that the upper end of the bushings also has a fine outer radius so that the bearing blocks can be easily guided onto them!

Then I cut them to a length of 14 mm, deburred them, and they're done. Fits like a glove....
