Not familiar with 396 cylinder head architecture, but is it possible that one or more of the rocker arm studs is threaded into the intake ports and there is oil coming into the ports from the top side, past the stud threads? I'm thinkin' that if a previous owner tossed the pressed-in studs for screw-ins, he would could have drilled through the top of the port roof before threading the hole for screw-in rocker studs. Then, if he didn't seal the threads or even if he did and the sealant has grown old and cracked out of there, that could be the problem, couldn't it?
