Years ago I saw a post that someone had found a combo of ARP studs that fit nicely to hold the valve covers in place. I can't find it for the life of me... Has anyone done this or have a part number that might work? Might be a nice upgrade and do a better job of holding the pressure firm on the gaskets.

On a second note, has anyone found a good arp option that works for the exhaust manifold?

 

They're torqued so lightly that any bolts are adequate. They are 1/4-20 thread. I like to use Allen head bolts for easier access than the 12 point heads the factory bolts use.
