Which way do the holes in the rocker arm shaft point up or down (for oiling the rocker)? Thanks. This is in a 1977 440.

 

Holes Down toward the head !!!!

 

mount those rocker shafts with the bottom holes 15 degrees toward the out side, I.E. the valves. from factory service manual. tighten rocker shaft bolts to 25 ft-lbs.. valve cover bolts to 40 INCH lbs. on the exhaust manifold nut to 30 ft lbs. DO use anti-seize compound on bolts on exhaust nuts. and ALL bolts on the bottom of truck. take to 60-70 % of full ft lbs first time, after 5-7 full heat cycles take to full torque, if it leeks before that take to full torque.
