When you set the cam/shim clearance do you then use the the same shim/valve followers and machine the valve?

I try to keep a common shim size, so I'll "tip the valves" (grind the valves tip) so the shims are the more center of the road/common shims.

if you crank your neck 85 degrees to the left....

you can see intake valve #2 is currently @ .010" (spec is .008"), with a .1122" shim. This means replacing with an .1142" shim should get me to spec. The other 2 intake valve, 5 and 6, are currently @ .008" with the .1122 shim. The other 13 were significantly tighter, and if I had a full stock of thin shims (.0984" through .1024") I might just shim it... but I TRY to think of the client/next guy... and if I keep common shim types in there, when this client goes for camshafts in his future... he should still be within standard - common size shim distances.

that is one way.... but I'd begin with a sizing set first to determine how much you'll need to machine from the tips. For example... sizing sets says you'll need 5.32mm, you can machine the bucket to 5.35mm and double check before final machining.

It would suck if you had to guess and over guessed.....
