Trick Flow 440 heads, The Real Deal?

I'm working on a new design for the intake gaskets. I'm going to use a valley plate with some little "bat wings" that I built to seal the intake to the valley. The bat wings have a bend at the bottom that gives me a place to make a nice seal with some RTV. I'm thinking this will seal up the motor really well and allow me to easily swap intake manifolds on the dyno.

LOOKS GOOD.
THAT SIMILAR TO THE INDY VALLEY PLATE?
