i was wondering if anybody had any suggestions on which kind of bolts to use since i am running aluminum heads. many people have told me that i should use undercut studs, instead of regular bolts. any truth to this???

 

The only real difference when bolting down an aluminum head is that you must use special head bolt washers to keep the bolt head from galling the soft aluminum when you torque it down. This is not hardware store quality stuff- they're special just for this purpose. Many companies sell these washers. Many good quality head bolt sets come with them automatically (ARP head bolts, for instance).

 

Anti-sieze is always a good idea to use on aluminum, too.

 

Not on a head bolt, it'll need thread sealant.

 

I was thinking header bolt, sorry.
