But I think before too much longer I'll be going with an NA filter housing myself, using a sandwitch plate and oil t-stat.

here this is what i was trying to expalin when you shim you block the passge pending how much you shim or if one is over shimmed
i have tested this on monet i had kicking around
(Im sure it has been covered before but I wanted to state it again in as few words as possible.
The stock oil cooler is a piss poor excuse for an oil cooler. The way it is designed is, if there is an over pressure between the pump and the filter some oil is bled out into the cooler and returned to the oil pan, so basically your oil gets cooled when your oil bypasses the filter and barely cools the engine at all. When your oil is the hottest and thinest it will never see the oil cooler.
It should also be mentioned that an off the shelf (joe blow consumer AN fitting, as opposed to an actual military spec AN fitting) -10 AN fitting will never have the same inside diameter as each other. I had a box full of -10 AN fittings and they all had a little different inside diameter some even had a smaller inside diameter than .46 inches. The ones I did use (coming out of the oil pump) I had to drill out to get them over .5 inch inside diameter. Just thought I should share that.)
