Cheers Tony.
Anyhow, New gasket fitted, head torqued down fluids added, then, shock horror, water dripping out around top edge of block in several places. Quick drain of radiator and head back off. Spoke to Robin who was as flummoxed as I. He suggested I re check the block face to ensure it was flat and to re check the height of the liners. So, straight edge out and checked down both sides all seemed good, then checked liner heights all around 7thou or tight 8thou. I know Robin prefers 5thou but he did say these should be ok. He did suggest a thin bead of liquid gasket on the water jacket face.
So thin bead it was, gasket back on, head back on, torqued up to 35 lb ft, then to 38 lb ft. Water added and hey presto no leaks. Cautiously stared her up and left to tick over for 45 mins, left to cool re torqued all good so far. Now had 2 runs out only 10 or so miles and all appears ok. Will do longer run on tuesday say 40-50 miles, then re-torque head. Then it will be fingers crossed etc etc. I must say that Robin has been mighty helpful and the sealing around the liners/head does appear to be superior to the copper gasket. Time will tell.
I am still going to rebuild the Triumph engine anyway just in case and after all 116bhp is tempting.
