    I just bought a Banks turbo setup for my 6.2. My engine has around 200K miles on it, uses little oil and runs real strong. The salesman at Banks told me I should replace my head gaskets because, "The extra cylinder pressure created by the boost will blow out your old ones." So I'm thinking I'll just buy a set and keep them on hand in case he turns out to be right. I personally like Fel-Pro gaskets (it's all I use), are they the best for this engine? Should I go ahead and change them when I do the turbo or wait and see if they go bad?

    I replaced mine before installing the turbo. If your not too concerned about blowing a head gasket at an inconvient time you could just wait, but with 200k on the original head gaskets it probly won't take long. When you do replace them I would use head gaskets for a 6.5L factory turbo diesel. They'll fit just like gaskets for a 6.2 but they're reinforced to handle a turbo.
    Good luck

    Hey! Can you keep notes on your turbo install? I've also got a 6.2L that is in dire need of more air (crazy altitude), and this might be a summer project for me.

    Technical writeup? I know I'd really appreciate it!

    I plan on doing a web page about the install, but it won't be any time soon. There are a couple of other things I need to fix before I do the turbo. Like the frame crack behind my steering box...

    I guess I'll just do it right the first time and do the head gaskets. It will be easier to do it when I have part of the engine taken apart anyway, than to wait until a week (or whatever) after I put it all together and take it all back apart.
