That's what I thought, but I asked the guy on the phone at the place I bought them from told me that they were 1/2", but as long as the dowels on the deck were new or in good condition, that they be enough to locate the head and 7/16" bolts would work. That doesn't seem like a good idea to me, but I'm not really sure. I'd feel better with some bushings or the stepped bolts, but since I've already got my ARP 7/16" bolts, I'd need a bushing.
I just don't know if the heads are drilled for 1/2" or not. Does anyone know if they are 7/16" or 1/2". AFR's website makes it kinda seem that they are drilled to 7/16", but it doesn't clearly say which. If you have 165's, what did you use?

Running a head made for a 1/2" hole with a 7/16" stud or bolt will leqd to head gasket issues eventually.
If anyone needs the bushings/washers I have a brand new set from ARP that I didn't need for a customers car and I will sell them cheaper then you can buy them. [email protected]

RICK91GT---- Do the bushings just sit on the top of the head and go down on the hole just a little or are they the full length of the hole?
