906 head capabilities?

I wasn’t there, and never say never…….. but…….
Since those heads have valves that are .350+ longer than factory heads, then any pushrods designed to work on factory heads…….. in theory would be way short on your heads.
But………mix n match rockers, lifters, cam base circle, etc…….. and you need what you need.
Yea I thought it was strange how much shorter the pushrods were coming out to be but the pushrod tool I had came out consistent on all the push rods.
