Pulled the other head off and those cylinders look good. I also pulled the pan off and on one of the crank counterweights is stamped 9/23/91 which leads me to believe that this engine has been rebuilt at that time. I also noticed some white goo in the pan and on the #7 rod, almost looks like assembly lube? All the mains and rods look good!
I put MMO in all the cylinders when i first got it, that's what's in those 3 cylinders
