Hoping to get head studs from ARP for my 2.5L. They don't make any specifically for the 2.5L, but the 4.0L may be the same size, which they do make studs for. I called ARP and to be sure, I'd need to know the size of the 2.5L head bolts to know if the 4.0 head studs would work to find other studs in their product line up that could fit.

Anyone know if the 4.0L and 2.5L use the same size head bolts. Or know the exact size of a 2000 2.5L head bolt?
