Re: Rollor Rocker stud problem
They are to short, you can either put hardened washers under the studs to raise them up or get some guide plates and cut them up to use as spacers or swap out to the 7/16 stud they may be the right length but Comp does not make self aligning in this size so you will be using guide plates maybe some one else does if you want a full roller rocker, or get your heads drilled and have inserts put in for standard threads.
http://www.machperformance.com/ sells a kit that includes studs and washers same short ARP studs and hardened washers. I was told they can also make the conversion to standard studs using inserts. I had heard other people on SYTY.net could do this for you too you just need to ask. I had this problem too I had called ARP and they wanted over $1000.00 just for 1 set of what i needed, I told them if they made them they could sell them. I bet if you get a GP going you could get enough people to make the price reasonable. You may want to ask ARP to look in their bins for a stud that will fit your application from a previous run someone had done. When I did my motor I had contacted ARP and they found enough studs right length with the metric bottom and 3/8 top for my motor. I guess I had gotten luckey, but I did wind up paying over $100.00 for the set shipping extra. I'm not sure if they had any left from the run I bought them from or not.
Good Luck
