What Piston for TF GenX255 Heads? What Aftermarket Pistons do you need to run with Trick Flow GenX255 Heads?
Will the L92/LS3 pistons work? Or do you need to use a LS7 Piston with the 12° valve angle?

Depends if you are FI. If NA, I'd think you'd want at LEAST 11.0:1. I believe the angle tips the valve up so you GAIN clearance. Unshrouding the valve.
