Hmmm, a 1991 *might* require adjustment. I don't recall. I'll see if I can dig up a '91 service manual at work.

do you know if the pushrods on a 2000+ motor are shorter?

 

i have '01 vortec heads on a carbed 91 block and when i went to torque them down, it bent the pushrods.

 

thanks!

There is no adjustment. You just tighten the rocker arm bolts down. 22 lb. ft. if I recall correctly.
