there is a "knurled" end, according to the manual I have this is only to indicate the length (and engine type, 1600/1800) of the pushrod..
but I put the pushrods next to eachother, with knurled ends at opposite ends, and the cap , or "nipple" on the end of the rod is longer on one tube than the other...
do I install knurled ends to the direction of cam followers, or to the direction of rocker arms?
