Joe, I noticed something in your last photo ("columnIn"). The oil filter-pressure gauge unit-hydraulic line fitting looks suspicious. I may be mistaken but your engine looks to have a connection not like others I have seen on these 356s.

Usually there is a four way brass fitting that fits into an outlet port (male 1/8" NPT). It has two holes for inverted flare fittings. One of these goes to the oil filter and the other (through a short tube) goes back into the engine for the hydraulic lifters. These fitting holes have a restriction in them where the others are full size. Lastly, it has a 1/8" NPT female fitting where the oil pressure gauge fits.

The conventional fitting, with restrictions, is important to maintain pressure while providing oil flow to the filter and lifters.

Yours looks different than this to me, but it is hard to tell from the photo. Just wanted to make you aware of this.
