Rocker Arm Interchangeability?

Hi all,
Just putting a question forward about using the 1952 Rocker Arms (inlet and exhaust) in a 1957 Rocker Box and in the build of a 1957 G80 engine. The books show different part numbers between 1952 and 1957. Can it be done? And what is the physical difference between the the 2 sets of Rocker Arms?

Cheers
Peter

I would say yes you can use them, but the later arms have grooves for better lubrication of the pushrod ends.

Hi Dave,
Thank you. I am going to take a Rocker Box apart now and do the comparison between the Rocker Arms in that box and the other set I recently purchased.

Cheers
Peter
