Rocker Stands For Magnum Valve Train??

I understand the shaft is the same size. What would you do about the hole being 7/16 now and the Hughes rockers being 5/16 thread on the bottom?

I guess I need to understand better. So they must have their own hardware then that goes with the shaft mounted rockers. I forgot you have seen them up close........Is that how they are??

If that is the case I will just stick with the Lash Caps I am ordering. I am getting really tired of all the crap I have been running into with this build and the magnum style heads. I will never, ever use this valve train set up again.
Shaft mounted LA style heads from now on. I will be ordering some new heads for my 349 stroker that will be LA style with out a doubt! Cheaper to set up also it seems. I got all the parts except the Heads for that one. I will have about 3k into that one from Carb to Pan.
