I'm going to be doing intake manifold gaskets, knock sensores, valley pan gasket etc on my son's '05 Tahoe next week. While in there, I would like to replace the coolant pipe gaskets. I was gonna use Felpro part ES73027. But talking to someone who did this on an '05 Denali, he used Dorman part 56390. But, I don't see that Dorman part 56390 is for an '05 Tahoe which I find odd seing as how they make it for many other '05 LS based engines. Can anyone confirm Dorman part 56390 will actually work? I ask because its much easier to get a hold of this part, than it is the Fel Pro part, at least near me.
