ARP head studs ???

[RIO5.0]

Do the studs have a concave washer or flat??? If I remember correctly the bolts use concave washers??

I need to buy washers and I'm insure on the type.... Thanks

i thought they were flat but its been a long while since i looked at them. have you tried the pictures on their site? or maybe summit?

Mine were flat.

I'm 99.9% mine were flat, but I'd have to pull a valvecover for that last .1%.

i will throw a wrench into everything. mine have a "recess" in the washer. i recall this because i initially had to double check to make sure it was facing correctly on the bolt. my bolts were purchased several years ago, so not sure if a change has taken place since.

I think flat is correct for studs and recessed for bolts...

Thanks....
