Run not walk away from anything that "Heath Diesel Sells".
He Buys stuff for retail cost puts his sticker on it calls it his and then re-sells it for double what it costs.
ARP manufacturers the studs which heath uses. Their is nothing special about them. There is a thread running around on one of the diesel pages with the proper length and thread pitch. You should be able to get the studs, nuts, washers for under 200.00
I hate seeing someone take advantage of someone. When "The diesel Page" was first founded Heath appeared to be looking to help people out. Somewhere along the way he got greedy and has been trying to take advantage of people. I know he needs to make a living but not ripping people off.
*Edit*
OMG 4-700 dollars for a set of injectors.............
