Is it torqued the same as a solid head bolt? I was a bit leary.

How do you identify '58 and earlier rockers?
Thanks,

Cosmo, up to 1958 the groove inside each rocker was centered, starting in 59 the groove is offset 1/4" so it no longer lined up with the supply hole in the shaft.
1951Chev1Ton, The torque is not mentioned but I torque them the same.
