GT40--ARP head bolt question--Pics!!!

[funkytrunk92]

So I got my ARP pn 154-3601 head bolts. I am concerned because they look different from my stock head bolts. They are not threaded as far as the stock ones and they have washers with them. I just want to make sure that I have the right thing, becuase I do not want to do another head gasket change for at least a few more months . Heres some pics for you stangnet experts out there. thanks

You will be fine. The factory bolts actually have way more threads than needed. Just make sure and use the washers and follow the ARP recommendations for bolt lube and torque.

The ARP bolts have a radius under the heads. The washers that come with the bolts have a chamfer cut in them. The radius under the bolt head mates up with the chamfer on the washer. Fail to do this and the bolts will never torque down properly.

All the bolts get antiseize under the bolt heads, and everything but the short head bolts get it on the threads. You need Teflon pipe dope or ARP sealant to coat the threads of the short head bolts. The short bolts go into the water jacket and will seep coolant if you don't use the sealant.

hey jr, just to clarify, becuase I am pretty sure that I did that wrong with the bolts. the flat side of the washers go to the block right? I pulled the heads and the washers were all different directions.
