318 stroker oil leak :(

Hey everyone I'm stumped on this one,

My 318 was rebuilt to a 392 with 302 heads and i used arp head studs and torqued to spec. Machine work and rotating assemly install was done by Carlson Machine in Salmon Arm BC:burnout: in 2010, but an injury stopped me from bolting it all up until January this year, then when i did get it all in the car a faulty alternator fried my wiring harness all the way to the dash :( so now i finally got it all together and successfully broke in the mutha thumpa cam with no issues :)

Problem is moderate oil leak on rear of block while running, (i can crank to 80psi with ignition grounded and not a drop of oil) oils pours enough to leave a drip trail down the road on its maiden voyage (only a half block and back home again) First i thought it was rear main seal leaking from sitting for so long but removed the inspection cover of the 904 auto trans and flywheel/flexplate both dry, oil pan gasket also looks dry except where oil is dripping down at the rear. The oil looks like it dripping from rear of both head gaskets and drips onto both exhaust pipes and also flowing from back of oil pan and down to oil drain plug.:wack: Oil pressure gauge tube is also wet but i checked it while running and revving and its a very minor leak not enough to cause my headaches. I while be taking care of this prob ASAP

question is shud i retorque the head studs and hope it cures my woes or do i need to pull the heads and do it all over? I'm nervous about retorquing because of the sealant on the "wet" studs and figure that to get proper torque I have to first back the bolt off the head studs and then retorque to spec? But wouldn't this cause the sealant to fail and thus leave me with water/oil leaks anyways???:blah5:

Any advice would be awesome, I want this beast running for our local Mopar show this weekend at O'keefe ranch in Vernon, BC Canada eh

Oh and the motor is in a 70 Dart swinger
