Jomar Stud Girdle

I'm ordering Jomar stud girdle #1143
To suit my super cobra jet heads but unsure what poly locks to get.
#1413 or # 1416

Depends on the rockerarms . What do you have?

B.T.W. myself and others can get you a better deal than the Jegs price.

Comp cams rockers,
Lem if you have them I can order girdle and poly locks

From what I found rockers have .562 slot. So am I correct with getting #1416
Thanks

those should take the .600" base nut. are they 1630-16 or 1830-16?

I just measured mine,and they are .600"
Where do I check 1630 or 1830 ?

.600 it is. It's a better deal than the .550".

Is it just the picture, or does that adjusting nut look extremely close to the rocker body in the first pic? The last pic seems to show a mark on the body - was the hex on the nut hitting it? Possibly need longer pushrods?

I'll get that looked at
Thanks
