The 7.350 rods you already have arent even the right size for your current setup so your **** is still going to be off.
7.4315 should be your current PR size with your TREX cam.

You are probly right about the lifters just being overly preloaded. But i know my setup works now, so I am gonna adjust the current to fit the new lobes and be done. Who knows, my heads could be cut even more. I do know When I previously put an LS6 intake on these heads, while torquing it down,you could hear it make a little popping noise as it slid down into place. It never cracked, I have checked, but it was a very tight fit and it would sit crooked until you torqued both sides down...HAHAHA...same thing with my FAST 90 intake now, except no popping noise, just crooked till torqued down. I had to go back and spray starting fluid around the intake until I got it tightened all the way down and stop leaking.

Normally you shim within .050 of coilbind.
On the PR issue, best advice is measure with a length checker.
