RHS head valve train geometry issue

Not just 20 minutes ago, I tried a set of PRW stainless rockers that fit great on the factory LA head, on the 360 LA-X. They are waaaaaay to long to work on the LAX head. I believe the LAX heads were designed that way on purpose.

The only thing I have used the LAX head for is flow testing and for converting to Chevy style stud mounted rocker arms. Hmmmm. I have to buy Hughes or Indy huh? Why am I not happy about that?
