850, rebuilt head, new rings. Used new graphite appearing head gasket with metal rings around pistons. Also used small amount of Yamahbond on gasket (each side) around each push rod opening (was told this was a common leak area). When engine fired up, after about 3 minutes, oil started to leak out of the front two studs that go up thru head and are held in place with washer and nut. Upon taking apart to investigate found pooled engine oil in left cylinder and other cylinder oil wet also. It appears pistons might have been pumping out oil. I torqued head down in manual suggested sequence and pounds (30 lbs except 20 lbs on the two leaking front studs). Gasket looked ok and no obvious signs of why it leaked so bad. I removed the two studs from the cylinder barrel and short thread was in down position, long threads in up position like it is supposed to be. Also after first leak, I let motor cool down and retorqued and it still leaked same amount. Anybody ever have this head gasket problem or ideas on what is going wrong? The only thing I have discovered is that the 2 studs don't seem to have much thread left when head tightened down. Thanks for your help.
