So I have pulled the heads for inspection and have found that the rear head has a bigger exhaust valve than the front head. The front measures 1 3/4" and the rear is 1 7/8" since it's the exhaust only would this be a problem? Rear head and piston are very dirty and it looks like had a head gasket leaking also. Pistons are both .010 over and seem a little loose going to pull the cylinders and measure . Any opinions will be greatly appreciated.IMG_20251122_154422431_HDR.jpg

Chances are the seat was too deep so an oversize valve fitted. On a stock motor it is a non-issue.
