Piston, rings, gaskets and the SS valve job. I put in a new piston and rings at the same time.
By the time I did the checks to figure out what shims I would need to order it would work out to probably more money than just having him do it while they had the head for the valve rework. I felt it was easier to have ken do the shimming so I would get the head back ready to install. Hey Scott, I did this same work to my 450X last year.
