Trick flow rocker shaft studs

Rat Bastid said
Why not use the bolts like MO suggested? There isn’t a reason to use studs there. I’d bolt that stuff down and get on with it.

Peace of mind really, the bolt holes in the rocker shaft pedestals are not helicoiled just tapped into the aluminium. I don't want to trash the threads so I would rather have studs there so I can get full thread engagement in the head don't have to take them back out once they're in.
But I might just be over thinking it.
Just to clarify I'm not using Trick flow heads - China castings.

I used these with my correction kit and PRW rockers. Studs are so much easier than a bolt with high pressure springs. They were long on the shaft side, but I wanted to be able to bottom the stud (and then back off 1/4 turn) and that's what McMaster had that was close.
