Numbers stamped on rocker arms

[Sixt8Chrgr]

Can someone tell me what these stamped numbers mean that are on the rockers?

Thanks,

Can I say I see something wrong on them ? Dunno about the stamped numbers, but IT LOOKS intake/exhaust rocker offset is wrong in some of them

Nacho,

I noticed that too but honestly did not know if was wrong or not. How should they be placed on the head? Are they out of order or an exhaust rocker on an intake valve or vise versa?

Thanks,

I guess we are looking at BB heads.

Every pair must be with one offset to one side and the other one to the other side. Look at the rocker seat against the valve steem and you'll notice which one must be matched with which one.

Is not really exhaust or intake deal because on heads the valves are not alternative. Valves are exhaust-intake-intake-exhauts-exhaust-intake-intake-exhaust. Is simple match the rocker offset with the valve offset. I think remember is simply left-right-left-right-left-right-left-right.

once again, dunno about the stamping. Wich BTW, some of the stamping must be also related with the offset

Yes they are big block heads.

Thanks for the info.
