A J Rocker stand help

we ran the old fuel Dart heads on our car for the last few years with stage 5 rocker gear. this season we are switching over to some stuff that A J made, with the extra stud hole on the bottom of the rocker stand. i was told that our old stands would work fine, but the geometry looks to be a little off to me. i need to find some standard ratio stands with the extra hole on the bottom to mock up on our motor to see if this is really the stand that i need to use. anyone willing to let me borrow a couple? i have a good 3 1/2 year old clutch guy that i can send out as collateral is needed. thanks
