valve train pushrod geometry setting, weird question... maybe not Options

[orange914]

following the step by step valve geometry i've got a few possible issues? when no shims used and exhaust and intake geometry is set the swivel feet are almost bottomed out (almost no adjustment left). so next it was shimmed with .025, the geo/swivel tightness got better (not so close to bottoming against swivel) when shimmed with .040 shims i have more space to adjust up left before swivel contacts rocker (3/4 to 1 turn).

bottom line it seems to work out better with .040 shims. with no shims it has wider range of measurements between each valve -and- closer swivel foot to rocker arms.

1] is .040 shim o.k.?

2] if o.k. is 3/4 to 1 turn until swivel foot hits the bottom of the (modified) rocker acceptable? yes they are o.e.m. swivels from a 2.7

3] if not o.k. can i remove .030 or ? more from rocker arm

4] if none of the above is good what am i needing to do to correct this?
