Default Re: 8BA compression issues

The leak down test resulted in leakage through the carburetor. I removed the intake manifold and the passenger side head. I checked TDC on number 1 and confirmed that with the piston at it's peak elevation on a dial indicator. The bump on the crankshaft pulley was aligned with the pointer. The valve lash was actually excessive being .018 at the narrowest. I have removed#2 intake and exhaust valve and guide. They were easily extracted. Unusually, both guides had the "o" ring installed. It makes me wonder whether the correct, later springs were used? The valve and the seats looked good. Any thoughts or suggestions?
