Why not get the 5/16x3/8 studs. How much spring pressure are you going to have? Most applications will be fine with the Comp Cams style conversion. Otherwise I don't think you can find 7/16 studs without tapping the existing holes. Again depending on the application not sure it's worth it.

I have done heads either way,and you don't need to mill the pads for guide plates.You could just leave them alone,and use the Harland Sharp shaft rockers.No guide plates,machining,or special treated pushrods needed.
