Mike and Neil, thanks for the compliments.
The word from Kibblewhite is the cams are a bit loose in their journals and I need to consider this when I measure the clearances for the shim adjustments. Originally I was going to swap cams between the street and race motor. Now it seems there are not a lot of miles left in the original head. It has new valves, guides, bigger inlet valves, racing springs, a port job, and the shim over bucket kit. It should give me many years of racing if I do not use it in the street.
A fellow in the Triumph club sold me this low mileage cylinder head for $300. I ordered a set of original 790cc cams from Triumph. They came over from England. This will be my street head. Eventually I will get it ported and have 2mm larger inlet valves installed. It is plenty good for now.
