Here’s my most recent findings, upon throwing the pushrods back in to try to start with stock MAF and IAT, i came across what I think may be the cause of my issue.

3/4 of my lifters have a “give” to them. When putting in the pushrod, i can push down on it and it will give a bit, then spring back up. 1/4 of them have 0 give at all. Like they are solid. Motor hasn’t been cranked in over a week, so is it possible there is still oil pressure in them?

I installed the pushrods and tightened down the rocker on one of the effected cylinders and did a leak down test. Air comes out both the intake and exhaust as apposed to coming out f the crank case on the other tested cyl.

When installed all lifters were seated again the cam lobe, oiling hole all facing same way. However after some debate i DID NOT soak them in oil before install. Just some assembly lube on the roller and cup.

Is it possible I’ve wiped out some of my lifters? They aren’t any crazy high dollar unit, just LS7s
