Billet Specialties Thermostat Housing?

I too fought leaking thermostat housing, different gaskets etc. I also tried the silicon "Real" gaskets which sealed great until I stood on the loud pedal and blew them out, twice.

The ONLY solution that has worked for me is the billet specialties, o-ringed housings. I have used 2 of them, same engine different intakes, never a drop.
