2270 Valvetrain Geometry, Learning my way though this build! Options

[vjb206]

Hey Folks!

I’m in the process of a 2270 build (I’m a bit of a n00b, but using this as a great learning experience) and have some questions I was hoping the collective wisdom of the board could help me out with…

Dual springs
I’m running a WebCam #163/86b. This cam calls for dual springs which I had my machinist install. Of course I read the Jake Raby Valvetrain Geometry article after my 1st trial-run of test-fitting the adjustable pushrod to gauge lift. The springs are –so tight– that I bent the pushrod. He warned us, so I can’t complain. My question is - will I do damage to the cam test-fitting like this? I can deal with a slightly bent adjustable pushrod here and there, but I don’t want to damage the internals. Thoughts?

Rocker assembly
Do I need a shim on either side of the rockers? Or can the rocker make contact with hexagonal support/blocks directly? I’m getting .004 on the feeler with just a solid spacer, 2 shims, 2 rockers, and the 2 support/blocks. This means that I have only 1 shim per rocker, leaving one side un-shimmed, and abutting up against either the support/block, or the solid center spacer. Is that problematic?

As usual, thanks in advance!
