I "think" thats what he means.
But it's not what I meant. If there was a restriction - not saying there was or wasn't - it would have been removed with the rest of the parts and block hardware to clean. If the guy tearing down wasn't really savvy he might have missed it or assumed it wasn't important. IMO, and understanding that I tend to like the minimum oil pressure for safety, given this was a race engine 50psi is too low, and the fact it never changed tells me the system had problems from the get-go. It should always change a little, and I would have wanted 80psi hot with whatever oil you run if it was expected to shift at 7K.
