superpieboy,

This is a 1962 261 engine with an original head, rocker arm assembly, and 58-62 solid lifters?

If your oil pressure is high, and oil is feeding into the rocker arm assembly, it seems that all your plumbing is installed correctly.

Did the engine shop install a new oil pump?

The oil pump has a "pressure regulator valve that is supposed to regulate oil pressure to approximately 35 psi at 2,000 rpm". This valve could be stuck and/or the journal in the oil pump head for the relief-valve plunger might be clogged, not allowing the spring-regulated plunger to move and provide pressure relief. There is picture of an "exploded"" oil pump in the Shop Manual (I looked at the 1960 Shop Manual).
