Trick Flow 440 heads, The Real Deal?

AndyF said
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.
