Haven't played with "Turkey Pans" per se', but have played with heat shields that go in between carb and intake. And most of us sitting here reading this know what the underside (and the inside) of a Holley looks like, perhaps more than we care to admit.

The main thing is to seal the intake and carb from vacuum leaks. A vacuum leak will upset the fuel/air ratio. With a 180 deg intake as shown, we want to seal the right and left sides from vacuum leaks as best as possible, although it's not absolutely critical that this be done. Use the thick gasket you've shown on the intake, use a 4 hole gasket between the sheet metal and the carb. Coat the mating surfaces with ordinary wheel bearing grease (even Vaselene will work).
