TrickFlow Issues

So my trick flow heads have shown up at long last and I'm running into problems with the rocker shaft hold downs and getting the rocker arms to line up correctly. So the rocker arms not lining up might be fixed by ordering a spacer shim kit from 440Source. I'm using CAT 1.6 roller rockers and when I use the included .125 spacers and .650 spacers I ordered from 440Source I actually can't get the shafts to lower onto the head. Once I take the .125 spacers out they will lower onto the heads but the rockers have a lot of side to side play and are not centered over the valve tips.

Now the rocker hold downs are a different problem that might be related to TF heads being different than other heads. I ordered 440Source rocker shaft hold down set and the long bolts proved in the set are too long. I don't know if this is a result of TF not drilling and tapping the two wide rocker perches as deep as others (the TF's are all the same depth) or I'm missing something. I've attached a pic for reference.

So as with this motor build one step forward 2 steps back....so frustrating.
