2014 Kohler command pro CH742 questions.

[Jday123]

Hello, I have a grasshopper 725K with a Kohler command pro CH742. The exhaust rocker arm bolt came loose and the arm rolled off the spring on Cylinder 1. I am in the process of putting new heads on it and have ran into a couple questions before I go any further. Of the 4 head studs the top 2 on both cylinders are threaded out about 2 or 3 threads. I wanted to make sure this is normal or not. Also anyone know the torque specs on the rocker arm bolts, and valve covers. Thanks!

All studs should go in approximately the same distance. This manual should help you. https://www.mymowerparts.com/pdf/Ko...ual-Command-CH18-CH20-CH22-CH23-CH25-CH26.pdf
