Oil pan leak

Hello everyone. I just completed a 7 yrs nuts and bolts ground up restoration on a 1949 Chevy truck and my motor has the following specs:
- Fresh (350) 4 bolt block decked bored and aligned (stoked down to a 302)
- (HEADS) 70 fuelie 2.02/1.60 valves all ported and polished with matching valve springs at set height
- (CRANK) Forged steel 3.000 stroke large journal 1178b first throw
- (RODS) Z28 with floating rist pins
- (PISTONS) plat & forged trw 11.80 to 1 compression ratio
- (Cam) Crane commander hyd lifters 488/467 at 1.5 matching lifters
- High volume oil pump, alum roller rockers, new push rods, etc.

It was just put on the road about a month ago and I continue to have constant front and rear oil pan leaks. My local mechanic shop has replaced the gasket 3 times to-date (tried 2 pieces and the thick 1 piece gaskets) an still leaking. We have also tried to glue the gasket on the block with spray glue, only put silicone in each front and rear seal cornors, etc. Everytime, due to a Fatman Fabrication front end, we had to jack up the motor a bit to get the pan out. Is it forming too much pressure...I have both a breather filter on one side and a PCV valve connected to my air filter on the other. It has an aluminum timming chain and oil pan cover that seems to align well...I don't know what to do anymore! Do we have to put it all together and leave it over-night for the silicone to dry? ...can someone help?
