Fordboy, you might be right. I do not have anything to look at or measure. The head went south Tuesday morning and the machinist is giving me a good price for doing the work. I remember your advice that there are several ways to get the intake flow the engine needs, cams, porting, and/or bigger intake valves. My advice to anyone building one of these engines is to use a standard Triumph 865cc exhaust cam, a standard Triumph 790c intake cam, a good multi angle valve job, a street port job, and bigger intake valves if PipeMax indicates they are needed. This will give good flow without the many and expensive mods for the hotter cams. Now I have so much money tied up in the cylinder head that I will buy an other used one in good condition for the street and use this one for racing, only.
Cereal, thanks for the advice. I will order some.
The indexing head seemed to be a dumb purchase. I do not have a mill. I need some brass plugs for the bungs with fine pitch metric threads. Chances of finding some in this backwater town are zip, so I turned up some on the lathe and figured out how to mill the flats on the drill press with the indexing head. The setup works great. Now the index head is starting to pay for itself.
