[2004.5 duramax LLY]

hey im doing head gaskets on my 2004.5 LLy i have plans to put arp studds in at the seme tiem and i am wondering what else i should be doing while im there and what product i should be using

I'd do the down pipe either MBRP or Diamond Eye, and fuel rail race plug or shim kit both by PPE. you'll kick yourself later if you dont , I did. and had to tear it all back apart to get the fuel rail off. do the EGR blocker plate too.
