Admiral- That is some precision machining. Quite a bit of lift, too. I think my 575M is only 9 mm, so that much lift and that much timing overlap is pretty wild tuning. No wonder she pumps out so much hp for only 2 liters.
When I put roller bearing lifters on a solid cam 327 in the olden days, it became very difficult to measure valve clearance. We always adjusted valve clearance with the engine hot and running, but the only way 500 clearance could be adjusted is cold by rotating the crankshaft, like on my earlier Ferraris with shims. Do you have to depress those springs to change shims?

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
