Quote, originally posted by dmonitto » Just wanted to give everyone an actual opinion on these studs. The Racewares are too short with a standard head spacer, meaning you have to back them out in order to get the nut on fully. After a Raceware stripped on the initial 20 ft-lbs torquing procedure, I called Issam to get a set of ARP's.
The ARP's are longer than the Racewares, and have more than enough length to accomodate a spacer with the stud bottomed out in the block. Also, the ARP's have a hex key in the top, so that if you had to adjust the length, you could do so without having to remove the head. ARP's also include their moly lube, unlike the Racewares which suggest using motor oil. Personally, I would never think about using the Racewares again now that there is an ARP option availible.
Fully agree installed a set of raceware on a 24v deffinitely too short. plus they don't have the key or anything to keep them in place when you do back them up so you can screw the nut down. I am glad you are selling these Issam I recommend arp to everyone.
