Hi all,
Been really lazy posting the results on the forum. My main reaction to these rockers is ‘WOW!!!!!’. I already had adjustable push rods on the engine so redid all the preloads etc and on starting it up I simply cannot believe the difference. The rocker gear is so quiet, all the mechanical ticking which these engines are known for if they have any degree of rocker wear, or poor quality parts is TOTALLY gone. The engine purrs at idle and when going up the revs sounds so smooth. I’m pretty astounded at the difference. Oil delivery to the rocker is good, it drips nicely from each rocker. After 1000 miles there is no visible wear when I dismantled.
What a modification!! I wish I have some more engines to do it to.
