I removed all of the exhaust shims yesterday.I replaced the shims with quarters so I could move on to the next.
I had a little trouble with the Motion Pro tool on the number one valves.The tool would slip off to the left only compressing the bucket on the left side.I had to place a small screwdriver in between the lobe and tool to make it work,all the others were good.
By doing the math,there is only one shim I can swap to get a good clearance.

Icerigger,The difference between a 290 and 285 shim is only .0019"!

The math.....devide the shim size by 25.4 to convert to inch.So 2.90mm devided by 25.4 = .1141".
A 2.85 shim is .1122".Hope this helps.
