You can see those 2 gallery bulges in the valley if the block has em & reportedly they can be drilled out if they are present but not drilled. easiest would be to tap into the 1/8 NPT sender port at the top rear of the block & T & run em to the back of the heads & drill horizontle into the threaded boss in the rear of the heads then drill down from the top at an angle in the threads in the rearmost pedestal. You'd have full time oiling with that as opposed to timed cam oiling so size the orifice to get the amt of volume you need.
