I put the flat side down, nothing in the instructions. Anyone else have instructions that tell you which side goes down? Haven't torqued them yet just in case.

The chamfer faces up on the washer.

do all the arp head stud kits come with tappered washers?

Are you referring to the chamfer on the inside hole of the washer? If so I installed mine down...I'm not too worried about it...they are washers...how can they really be installed wrong unless the chamfer is for something special...

I just installed a set of ARPs with the instructions and still wasn't SURE which way the chamferred side was supposed to go. The wording is just that ambiguous. Even though I wasn't sure it made more sense to install them with the chamfer toward the bolt head side so that's what I did.

The chamfer is to accomodate the radius under a bolt head. If you're using the washers with studs, there should be no problem either way. If you're using them with head bolts, you definitely want the chamfer facing up. I hope that saves someone a potential future headache!

Tightening was a little strange too. The nuts would get easier to turn during the tightening sometimes. Kind of hard to explain, but you would be turning the nut pushing on the wrench and then it would get easy then hard again. Weird.

Oops that dont sound right there should be no easy hard as you torque. when I installed my stud bolt I put on molly lube on bottom thread, as it gets to bottom out you will hear compressed air poping out as it bottoms, did you make sure 1000% those holes were perfectly dry of oil and coolant, or that the studs were all the way in the block. cheers

Yesiree. Once advantage I have is I brought a boroscope home from work, those threads were clean as a whistle before the studs went in. Someone told me to back off all the nuts and start over, but ARP doesn't recommend this on a MLS gasket so I think I will leave it alone.

why isn't this recommended. what about the people who are checking ptv clearence where the head goes on and off a couple of times, would the gasket still be ok?

I think it depends on the gasket. For PV check (I didn't both because my cam is pretty small) I was going to use the old gasket so the new one wouldn't be crushed.
