Head stud question. I put them in today, read the directions from ARP and they dont say which way the bevel on the washers go, I would assume down. Am I right?
Also, on the MLS gaskets I assume they are different than the stock graphite gaskets in the way they go on the motor. I mean that the graphite say to put "this side up" and the MLS can go either way as long as you put the label "front" to the front.

I'll be putting mine on next week, how much trouble did you have doing them? And did you do it with the engine in the car? What technique did you use, ppl have told me to put the studs all the way in back it out a 1/4 of a turn then torque the nut on top? Sorry for the Hijack .. figured it was the same topic..

Thanks, so your saying that with the washer on the head you should be able to see the bevel? Why does ARP not specify this in the directions?

Oh and they studs go in hand tight (as per ARP's instructions), Ive never heard anything about backing them out a 1/4 turn.
same here never heard about backing out 1/4 turn. most make them hand tight some do hand tight plus a very small amount with a allen key.
For the washers i dont think it matters which way they go on. Ive seen the installed both ways, For my engine i did install them up cause i feel better with the larger area on alum

The chamfer side is supposed to contact the nut on the head stud...its supposed to eliminate any stress risers that could be present...metal burrs and those types of things that could be imposed on the nut and cause the nut fail. So with the chamfer up you are guaranteed that the nut is only contacting the flat part of the washer and not the edged of the hole. Make sense?

Yes. Thanks, that makes good sense.

The chamfer has a edge to just in a different spot. Plus we are putting more load on a smaller area of the nut should stress the nut more? how would a metal burrs cause a nut to fail its a non moving part ?
Just a guess here im thinking the chamfer is to keep from causing any loading on the bottom threads of the nut so they wont dig into the stud but i have no hard data to back this up.
Im just wondering where did you hear that at ?
