push rods came so this is number 1. I have .060 preload maybe a little more Iíll ck into that later. All the patterns are very close to these Iím a little concerned by that with the gap at the lifters over sized

Glaser67 is starting off with a positive reputation.
It believe it would be difficult to get it much better than that with pedestal mounts, If it were me I'd run it without a second thought, assuming the preload is what the rocker manufacturer specs. Others may chime in with ways to narrow the pattern, perhaps center it, but if its even possible, you would have to make very precise measurements. On a nice street build like you got, I'd say you are easily within spec. I'd run it without a doubt.

thanks for the input my abilities are not up to get much better need to measure the preload and maybe see what the small shim looks like

Defiantly try the shim, you have nothing to lose. For the preload, it can be equated by the turn of the bolt. I'm too lazy to do the math, but if you call the rocker manufacturer, i bet they could tel you. For my scorpions, it was between a quarter and one full turn after zero lash to specified torque. Worth a call to them.

Might I ask how you are performing the test? Is the lifter pumped? Packed? Or are you using a lighter spring? So long as its not collapsing, you're alright.

Just me but I think .060 preload may be too much for the lifter to handle. The patterns look fine. Too much preload and the valves will stay open. You could try running it like that and see if that's the case. Then if they do, add shims to loosen them up

Iím thinking that way but with my upper manifold/EFI over the rt head it would be a lot of extra work at this point Iím checking with the shims at lest on #1 and which ever valves are closed at that point on the crank/cam

would it do any harm to use both of the shims I have at the same time under different valves that is one under intake one under exhaust
oh I forgot I get to have a tooth removed today how fun!

Not sure what you're asking about here. Having teeth pulled is a piece of cake now, just have em put you under first.
