Source for 4d55 or 4d56 head bolts in US???
I was putting my new head on and noticed one of my head bolts (M12X1.25X105mm Socket Cap) looks questionable. Does anyone know of a reasonably priced speedyish source for these bolts? Or maybe someone has a few extra collecting dust somewhere???
Try a local auto parts store or you will have to order from ARP and probably a full set which are a higher priced kit.
If the bolt will survive the torque, go with it. How often do you do head removals on the truck? It's not like your doing them like oil changes and be sure to re-torque the head in about 500 miles or you will be doing a head gasket on your next tuneup.
any fasteners companies within your radius will have one, bring one with you if you go looking.
Thanks! I was able to clean it up with a die.
Putting it back together on Monday.
