My 28 also has 50 on all 4 cylinders, has good power and doesn't burn oil, so I think that's fine. If all 4 are equal and the engine doesn't burn oil, I'd even settle for as low as 45 lbs. before working it over.
It does have a noise I am going to check out though, so I'll be pulling it for that reason, and use another good short block in the meantime. I think it's piston slap. but won't know for sure until I take it apart.
