You do need self-aligning rockers. The old heads had pushrod guide holes, the new ones just have holes. So, for the new heads, the rocker arm was made with a groove that maintained its position on the top of the valve stem. Self-aligning roller tip rockers will have two washers on the ends of the roller that keep it from sliding off the valve stem.
John's ride to the cemetery, his beloved Billings OK bus, The Baby Elephant!! Traveling in style!! As his service was starting I couldn't figure out what the music was, heavy on a flute in a jaunty...
