Arp nuts + crower springs = bitch

[Super Bleeder!!]

I'm having a helluva time getting the arp nuts onth their studs, as the corner ones interfer with the crower springs.

I tried lifting the head and slowly lowering it down while tightening the nuts, but to no avail.

Anyone else had this experience, and if so how did you remedy it?

I had a problem with them too... I had no choice but to "help" the washer down with a socket and hammer. Looked like it bent the edge of the seat a little, but nothing else. Not the way I like to do things, but I saw no other way.

[Super Bleeder!!]

The washers i can get down there no problem, its the nuts that are rubbing the springs.

[Matt D.]

Hmm, I can't remember... I don't remember the spring getting caught under the nut, but they did touch as I wound it down and just squeezed by.

Are you sure you're using ARP nuts? I think they were 14mm 12-points. They're much smaller in diameter than the washers and even with the socket on them, is not as wide as the nut seat, or the washer. I didn't have any issues with mine and the crowers.

[Super Bleeder!!]

Yes, 14mm 12pts and they are indeed smaller than the washers.

Not all of the holes are giving me trouble, just the corner ones.

It just occurred to me that this could be an issue unique to me since i'm using a 2g head with the holes drilled out to fit 1g arp studs. I'm sure the 2g arp stuff would fit, but its too late for that now! :(

I need to figure this out!

You're an engineer, just redesign everything. :D

[Super Bleeder!!]

You're a lot closer to an engineer than i am at this point!

Its been suggested i just shave down the nuts giving me trouble (about 1mm).

Its not the prettiest or even the best solution, but considering its just a static fastener it will probably work.

Wierd. I had absolutely no problems with mine. I had to put the washers on first, but I have no problem with the nuts.

^^ Are you using a 2g head?
