It's possible I may have over rev'd it at Del Mar. I put the TH350 in 1 and ran the course without shifting.
The lifters are solid. I will attempt to pull them out tomorrow. I need to check the springs for binding or a stuck valve. I'm also going to drain the oil to check for metal and try to rotate the crank and see if it moves freely.
I might as well pull the other head off now too..seems like good practice
