I could see the reasoning why that wouldn't be kosher.

You are removing the three screws that hold the head onto the cylinder. If you don't re tighten the screws enough (secure them to a likely undisclosed torque spec / thread locker / etc), there is a chance the head could come loose with 120psi behind it.

Ya our LRI said the same thing.

Your LRI and his LRI are the same LRI... You're from the same team!

Personally, I would make the same argument with my team and tell them not to do it. I could understand the argument for R65-C, but I don't this this is what the GDC had in mind for that particular rule. This is also something that I think most inspectors wouldn't notice or think about when inspecting. But as an LRI, I feel I have to hold my team to a very strict interpretation of the rules during build. It keeps them from having problems during inspection, and avoids any risk of an inspector thinking "i didn't think that was legal, but it's the LRI's team and I don't want to look like an idiot..."
