Must be Xmas....
Mrs P was feeling very generous today & let me assemble the head in the warmth of the kitchen.....
So.... got the new APE h/duty springs, extra shims & new stem seals ready.
All valves have been cleaned & lapped in a few weeks back......
Prised the old stem seal off (brittle & sh*te) and greased the valve stems...
Fit new seals with a touch of grease.... still a bit fiddly
Valve tool at the ready, all valves clearly marked for re-insertion....
A spring seat is sat under the spring set and the top retainer popped onto the springs then put in place over the valve. Only compress springs
JUST enuff to get the collets fitted, so as not too over squash them.
All nicely fitted...........and time to fit the buckets & shims.....
I had measured gaps before stripping it down, so new what sizes were needed. Only had to buy 2 x shims coz I swapped some about to get required clearance (0.010 +/- 0.005mm).
The head is gas flowed & all looks OK...
Awaiting the blasting of the barrel & casings then I can start to get the engine back together & in the frame.....

And on the 7th day... Zeds were created!
