An update for those interested.
After troubles and tribulations, various, I found that honing the valve guides with an old valve stem and fine paste, polishing the valve stems with 1200 grade paper and oil was the solution. I had bought and tried a suitable sized ream, which almost fell down the holes, which is why I fell back on honing.
Sadly Ivor the valve guide cleaner you recommended seems not to be available (no reply from the company concerned). One of the difficulties was in refitting the valve cotters, they are little buggers when working over the wing of an RP even though I removed the manifold. They hide in the most awkward places!
In all I had the head off three times and all the valves twice. In addition at one point the starter that came with the engine stopped working, nothing at all. Removed it to find the pinion nut loose in the bell housing, no split pin through the shaft!
I have just driven 5 miles and tightened the head down, now to get a good number of miles on the clock before setting off for The Dales in two weeks time for a short break, in the Austin!
Thanks all for your thoughts and ideas, you were right, I would in future if fitting a rebuilt but longtime stored engine, definitely strip the valve gear and probably the ancillaries, for correct fastening, possible dryness and general workmanship.
