When a SBC has oil leaks on the passenfgers side ya always gotta ask of there is a bolt and sealer on the front mount bolt that goes into the fuel pump pushrod cavity.

Next suspect is the rear seal of the intake manifold. I haven't used anything but a tall bead of "the Right Stuff' for end seal gaskets in a couple decades. Once in a great while I'll mess up setting the intake into place and get a leak (more with this stupid tunnelram and any others) But a weep at the corners will run down between gap between the head and block created by the headgasket,, and drip off. Depending on starter (full size or mini and clocking) I've had it drip onto the headers. If you used the cork or neopren end gaskets I'd sure take a GOOD look with a mirror to see if there is a weep at the back of the intake.

FYI there is no oil (pressurized or otherwise) passing through the head except what is pumped UP the pushrods, and the drainback holes that return the oil to the INTAKE GALLEY. If you have oil on the outboard side of the head, it's coming from the rocker cover, or weeping down from the intake end seals.

Just a word of caution,,, oil on the headers is a real potential for a underhood fire. If worst comes to worst, get a bottle of the dye and a light to trace the source.
