thanks for looking into this.. The stem size on the 2600 valves is the same on both sides(intake and exhaust) 9.40mm. The valves are indeed of different sizes but the stems diameter is the same...
let me know if you have any shims that would work..
i am looking for the followings
If anyone has extra ones let me know..
I read in the Jim K's red book that one can use VW flat shims and they work great. I haven't tried it, but it makes sense. The larger diameter VW shims will weigh a bit more, but you're not revving these things all that high, and the degrees of rock would actually be less than a smaller diameter shim. Plus, they're cheap and easily obtained.
