Stud Girdles / Stud Alignment

Chad E532 · 12-21-2009, 10:41 PM

Is it typical when installing a stud girdle set that the rockers are out of location by 0.100" or so center to center? I just bought a set of the Jegs house brand for small block chev and they will tighten down, but they are moving the studs around more than I figured they would.
Thanks,
Chad

Wow , .100 seems like alot, sometimes really cheapo rocker studs have alot of runout in them. ARP studs run real true.

what heads/what motor?

AFR 195 eliminator heads with ARP studs. The tech guy at Jegs recommended that I return their house brand set and go to the AFR since the machining maybe slightly different. That is what I get for trying to save a little money and go the cheaper route.
Thanks,

I believe that the valves in AFR heads are relocated to provide clearance for the intake ports so that it is imperative that the stud girdle be machined for the particular AFR head. I would suggest contacting AFR, give them the serial numbers from the head and let them tell you which stud girdle would be the correct fit!!

I run both the AFR 210cc and the 227cc heads. On the 210cc heads I use a regular Moroso SBC stud girdle and ARP studs with no problem what so ever and everything lines up perfect. Now on the 227 they relocate the valve to clear the intake port and you have to run their girdle as it is machined correctly and offset rockers or run shaft rockers. I am pretty sure the 195cc heads use standard valve locations, I would think its either a machining problem with the jegs girdle or studs that dont run true.

They may have 40\60 stud/valve spacing like the 867 pontiac heads(for SBC) If thats the case you may find some used ones floating around,but to get new you would have to buy from Crane?,Comp, Jomar,AFR
