These engines were originally equipped with this kind of stud. However, due to production differences, it is possible some 289 or early 302 engines may be encountered that are equipped with positive stop rocker arm mounting studs. Before following this procedure, verify that the rocker arm mounting studs do not incorporate a positive stop shoulder. On studs without a positive stop, the shank portion of the stud that is exposed just above the cylinder head is the same diameter as the threaded portion, at the top of the stud is of greater diameter than the threaded portion, this identifies it as a positive stop rocker arm stud and the procedure for the 351 engine should be followed. Crank the engine until No. 1 cylinder is at TDC of the compression stroke and the timing pointer is aligned with the mark on the crankshaft damper. Scribe a mark on the damper at this point. Scribe three more marks on the damper, dividing the damper into quarters (see illustration). With mark A aligned with the timing pointer, adjust the valves on No. 1 cylinder by backing off the adjusting nut until the pushrod has free-play in it. Then, tighten the nut until there is no free-play in the rocker arm. This can be determined by turning the pushrod while tightening the nut; when the pushrod can no longer be turned, all clearance has been removed. After the clearance has been removed, tighten the nut an additional 1⁄4 of a turn. Repeat this procedure for each valve, turning the crankshaft 1⁄4 turn to the next mark each time and following the engine firing order of 1-5-4-2-6-3-7-8. Positive stop adjustment procedure: Rocker arm tighten specifications are: 302 and 351 W — tighten the nut until it contacts the rocker shoulder, then tighten to 18–20 ft. lbs.; 351 C — tighten the bolt to 18–25 ft. lbs.; 429 — tighten the nut until it contacts rocker shoulder, then tighten to 18–22 ft. lbs. So in a way they all adjust by the rocker arms. I have seen engines that were sick until we backed off the nut from the positive stop then double nutted them. ** MERCH Site ** https://troysgarage.myspreadshop.com/ Send me stuff: Troy's Garage YouTube Channel 4956 West 6200 South - Box 235 Salt Lake City, UT 84118 Check me out in other places: Instagram:   / troysgarage
