Miss and tick after head job

I would try moving the injector, or at least check it for copper washer damage as previously recommended. Are you able to do a relative compression check with ae? If so, I would do that before tearing it apart.

Its going to be a few days before i can get back into it. Im gonna check the injector out before i pull that head again

Pulled head piston has valve marks, i dont see a crack in the piston. Removed the #4 exhaust valves, one valve was mushroomed on top had to file down to get out. Rolled valves neither look bent. Lookina at the valves one is longer than the other by .110" also they dont have the grind on on the seat end. That dosnt make sense to me why would one valve be almost a 1/8th inch longer? The seats dont look bad. Im going to change seals while im there

Why would one exhaust valve be longer?
