Easy way to see if the heads are early is the 2 out bolt holes in the valve cover area are recessed way down in the head. Newer ones supposedly are about equal with rest of the holes. (haven't seen a newer style head though)

Getting a socket on that bolt (if nut it needs a smaller head).

And this is why I was under the impression that it's possible even studs may not have enough threads to allow the nut to be torqued far enough to provide enough clamping force.

Not sure if that's true or not, but that was my logic. Would like to hear comments on that.

I don't think there's a specific set of studs offered by ARP for the E-Heads or not.
