I see you point on the tall head gasket guys, I will need to do the tests that Schex3x has suggested. Where did you get that measuring tube thingy? I want one 
I am going to use some puddy on the piston to find out what the valve clearance is. Also going to talk to Woods on Monday about the w6h. I really would like to get to 100hp now that Im in it. Many Thanks to all!

as far as measuring the deck height the feeler gauges will get you close but you really need this tool for accuracy

search "buret" on ebay, you'll need the 100ml/cc size

BUT - branch heads have a smaller combustion chamber AND un shrouded valves, re directed ports to take advantage of intake track speed, combine that with a mechanical advancer he uses in the ignition and total advance comes out at 1800 ( they vary ) and a free flowing exhaust - i believe a typo in the 45 MM carb it was most likely a 42 MM and you can streach that cam out - look how early the intake opens and closes = 10 X 30 = so the motor traps static and breathes very well
you get lots and lots of power and you get it very quick < the quick is the key behind the combo -- good find --
