TrickFlow 190 Issue

I have a set here that I purchased in April 2019. After a couple years of scrounging parts I am finally able to use them or so I thought... with all 10 head studs in the block the heads will not sit on the dowels as they should. So I pulled all but the corner studs, set the head on the block and it sits as it should. I start putting studs in 1 by 1 looking for an issue. The long stud between cylinders 5 and 7 will not thread in as it should. I checked both heads on both sides. The issue moves to between cylinders 2 and 4 on the other side. Looks to be the hole location in the head. Best I can tell the hole is too high (biased intake side). I have some more checking to do to verify but at this point it looks like the hole is in the wrong location. I'm waiting to hear back from Trickflow. The fix is as simple as plunging an end mill in there to slightly slot the hole I think. I assume there's plenty of material there but waiting to hear back to see what they want to do.
