Tap off the oil pressure fitting on the driver's side with a T fitting and run a piece of 3/16" tubing around the back of the cylinder head to the 1/8" pipe thread port at the center of the head above the pushrod cover. I like to use a piece of 3/16" steel brake line if copper tubing that size is hard to find. This bypasses the internal passageways and supplies oil to the rockers. Some people put a flow control needle valve into the line to regulate the oil flow to the head.
