It looks like I need to replace my head gasket. Holy crap ARP studs are expensive. Anyways, any recommendations as to what I should do while I'm in there? I take it the Mahle gaskets are the ones to use? Is there any reason to take the head to a shop? Any inspections or anything I should do with the head while it's off? I already installed the 60# valve springs on the I&E. Thanks.
