Starting out with a .590 solid flat tappet. I did have to use a lash cap to get geometry correct and it did help the clearance also. I thought about making an offset block but that would make the PR clearance worse and everything I did with the lash caps I would have to re-do.
Assuming you are using a standard length valve, and an .080" lash cap, the geometry ought to be near perfect, unless something is really out of whack. You might be able to get by with a thick walled 5/16th pushrod and save some aggravation.  Is this the Mopar 590 cam?
