anyone know if someone makes a rocker arm stud to convert the non-adjustable bolt to a stud so i can run roller rockers. they are 3/8 holes regular bb is 7/16 called ARP they were no help

Arp makes them, I've bought several sets. I'll look around for a part number

I've got a set sitting here. Upgraded heads so don't need those. If you're interested let me know.

Found them from comp cams. rather use arp they insist they dont make them. Thanks for the input

what is the thread count on your 3/8 holes. ARP makes 3/8-24 listed for SBC

never mind my previous post. all were listed with 7/16 base. sorry.

135-7102 is the part number listed with jegs for gen5/6 3/8-16 x 7/16 -20

Thanks for the part # Unlimited jd Exactly what i needed Arp tecs said they did not make them, I called twice and got two different people Unbelievable.

if the heads are off i would get them drilled&tapped to 7/16-14 thread.that is what all the mark 4 engines are.
