Ok so spent some time with it today.
When I first put it together for mock up I think I may have had a spacer in a wrong spot pushing the rocker arm closer to the tight spot .
Looked at it today moved spacers around so rockers were centered on valve tips and ended up with about .020 clearance at the tight spot , push Rod fat end down.
But tried it fat end up just for kicks and almost doubled the clearance.

Thanks for all the replies. Couldn’t do it without you guys!!
