Don't feed from the turbo the oil is hotter , if you feed before with a tee not sure how to check that you have enough flow to both with out some way to if there is back pressure at the tee
I'd re-torque them all to spec 13# is not as tight as some specs ,my 2h is less bur my little JD tractor is higher
With a new head I'd check all the torgue's
