It would show us exactly which parts you're working with. There are several different 90 degree adapters and center bolts along with gasket kit numbers. Block surface would be nice also.
You mention "wagon wheel" gasket, I am willing to bet that as you tighten the center bolt it grabs the "hub" which draws the "spokes" inward causing the "rim" to distort enough to cause a leak. :thankyou:
