Thanks guys,
I looked over lunch and discovered several different number stamped on them.
25,40,38 on the face facing the front of the engine.
Then on one of them I saw an 8 on the opposite side.
I believe that i have the 54 -57 arms/oiling tube as the tube looks "field modified"
I am just going to take the front rocker arm off and look at it maybe this weekend.
Thanks for all the information
Mark
