My '60 tr3a has strange numbers and would like advice as to what to do. The service manual says 120 psi. I have: #1=155, #2=160, #3=115, #4=107. With a squirt of oil in # 3, it goes to125. Looking for a blown head gasket. Also, the#4 intake valve lash will not set right . I run out of thread trying to get more than just a small lash. Could it be a bent stem? It has about 90K on the speedo and should I pull the head? Thanks, Le
 
I'd pull the head. Could be a blown gasket, but I think you'll find bad valves and possibly a bad pushrod on #4 intake.
