I've checked with the sponsors and no one provides a package for only a head install, so this is what I found: http://gmperformancepartszone.com/cy...ar-p-6016.html

Is this what I need for Patriot 5.3 heads on a 99 ls1? I checked the heads and they don't appear to have the notch in the back of the heads, so I figured the gaskets for an 02 ls1 were what I needed. Is this correct?

And I would love to buy this stuff from a sponsor priced competitively, so if anyone can find something I missed and point me in the right direction I'll gladly support our sponsors.
