I need to know what the specs are for the $1200 Mopar Head stud kit. Part Number P5007912
Most places are running out of stock so they are getting hard to find.
That said, I talked to ARP a few months back and they said they had nothing in their listings for the W9-RP. BUT if I had the specs they could get something together for me.
I know they are 1/2" dia. in the block and 7/16" dia. through the head. There are 3 different lengths. 2 sets are 10 pieces and 1 set is 16 pieces. 12-point nuts.
If I can get the lengths I think they could figure out the rest and put together an affordable set.
If someone knows all the details that would be awesome.
I used to have a set but "Storage Thieves" wanted them I guess!

There’s a place called Allens Fasteners on the net. They carry individual arp studs. I realize what you need are the actual dimensions, but you can come up with that by measuring the head/ block.

Not sure I the RP studs are different, but Kent Ritter put me together my sets of 'stepped' W9 studs. Was much more affordable than tracking down pre-packaged kits. Curious as to why regular W9 heads would need "stepped" studs. The ones I use with my W9 heads are not stepped. Thanks!

Here is a cutaway of a rp head. The entire row of bolts between the ports are 7/16. The heads are much taller than a standard w9 also.
