Great information all. I will lap the two valves and test with gasoline. After assembly I will do a leak down test with compressed air since it is already setup.
On the other head (driver side) there is a faint compressed air leak on one exhaust valve. It is unlikely that gasoline would leak through that valve since the 85 PSI air leak is only barely detectable.
Before assembly I will measure the volume of the combustion chamber.
Thank you all.
