ARP Crank Studs for 318LA

I have been informed from ARP that they were not aware of this problem and purchasing a ARP bolt that is the stock length is the correct way. I have to buy it from CV Products (FYI there number is 1-800-448-1223) Will cost around 10.00 shipped to my door. I started with a very good base and didn't have to turn the crank. Had the whole assembly balanced and they said it was extremly straight for a stock crank. I installed the crank with the ARP studs in place and all the clearances on all 5 journals was .0015 and can rotate it by hand. I was told by the machine shop that if it would rotate by hand after I torgued the studs I didn't have to linebore it. If it would bind up at all I would have it Linebored no questions.
