Pressure test heads?

[Bluedemon6.0]

Quick question, I have my heads off to stud. Do I need to have the heads pressure tested? I posted the same question on the thread I started for arp stud quest. I'm not having any problems with the heads, just putting studs in. I'm taking the heads to napa tommorrow so give me your thoughts.
Thanks-Steven.

Ok, I going to find somebody to have the heads pressure tested. I have a problem, I need a tool to remove the glow plugs. I bought one but I can't find it, any ideas? Can i make one? I got the heads ready to come off minus the glow plug removal tool.
