Does any body have a ARP LS2 head stud (flanged nut 7/16"+ 20) ,i lost one and cant find it . I could order one from ARP but it will take 5 to 7 days to get here in Kentucky. Trying to get my new 418cid in my T/A.

 

I had the same problem a while back, just had to have one shipped from ARP. Turns out the nut wasn't lost but had somehow dropped into the lifter cup which I didn't realize until after I put the heads on and one pushrod wouldn't descend into the lifter. I guess I'm saying two things here, make sure that didn't happen to you, and good luck procuring one.

 

I counted them before i started in stalling them and notice i was missing one
