Pedestal Mount Rockers Shim Question

OK here are the specs of the engine relevent to the question

.040 302
Ported E7's, Surfaced .007" Just to make flat
FMS E-303 Cam
93-95 Cobra 1.7 RR's
Stock Roller Lifters
Stock Push rods
PBM .550 max lift springs
Felpro Head gaskets
Felpro head bolts

When I was installing the rockers, when I went to torque them to 25 ft/lb, I noticed that they were opening the intake and the exhaust valves. I ordered the Jegs Pedestal Rocker Shim kit with a .030, and a .060 shim pack. I installed all the .030 shims, and while I don't have any valves opening, I have some that have more slack then I feel they should have. I haven't primed the engine yet, and I am hoping that the slack will go away once the lifters pump up. They have been soaking in oil for over 2 years now... So I am not sure what will happen.

So I guess my question is: Am I doing something wrong? I have never built an engine with a non-adjustable valvetrain. Any advise would be welcomed!!

Thanks again, sorry for the long post, just want to be thorough. If you need anymore info, please, please ask!!

Yes. I noticed that the bast circle from the stock cam (what I think was a stock cam) to the E-cam has a different base circle. The E has a larger base circle. something in the range of .030 larger if memory serves me. I checked them with an outside micrometer.

no one else? Bueler?
