I know the second design for the 04+ is metal, but not the 97-03.

And that link is for vortec 305's and 350's as well as the 4300, 3100, 3400. No mention of the 3800... Which isn't a chevy engine, unlike the others mentioned here....
I had this done about a year ago at Midas muffler for my 3.1L 2001 GP. The gasket was updated back in 2004 so any Felpro LIM gasket purchased after that date has the updated design. Sorry for any confusion on this guy's. I just want to be as accurate as possible so others can learn. I don't work for Felpro (I'm a UPS driver). I haven't heard of any problems with the updated Felpro LIM gasket so I feel they that if anyone buy's them and installs them correctly they should be good to go. I would recommend people flush out there Dex-cool (unless their car is under warranty) and put in some universal coolant instead. In no way shape or form should people keep Dex-cool in for 5 years or 150,000 miles like GM recommends. Who wants to take a chance on Dex-cool potentially eating up there new gasket. It's not a chance i'm willing to take...
