Whilst almost bent double with abdominal pains due to some weird virus going round at the moment, I still managed to get one of the heads built up.
First off was a final scrub and clean in a hot and soapy degreaser bath to remove and last blasting media and lapping compound.


Then the original retainers and collets got the usual 3 stage clean up…



I then measured up the collets to the recess in the valve stem and found they were a little on the loose side. With security in mind, I set out matching them up in pairs, choosing a valve for them to live with, then using 180 grit wet n dry, I planed the mating surfaces of both halves until they were a snug fit with just the tiniest gap between them to ensure a tight fit.


The valve stems were given a final polish then cleaned, greased and placed in what should be there home for a very long time.


Decided another insurance would be new genuine springs, as the old ones have stood too long for my liking and some had lost a little strength and dimension from standing compressed for so long.

Spring compressor did its usual wonderful job allowing the collects to be fitted up…

And there we are – you can see the tiny gap between the collets.

And the head all done, bagged up clean and safe, waiting for the rocker assembly.


Not much, but another small milestone…
