Just had chance to read you post I was on my phone PITA to read with my old eyes.

I did inquire about having a set of W-9 heads ported by you, but when you answered a couple of my questions with " IT'S NOT WORTH THE EFFORT", I realized that what you are selling is not what I am trying to do with my combination and not worth me buying. ANYTHING that will make more power, quicker ET's, more

What you asked about was rolling the head over and I stand by what I said not worth it for making power unless it was used to get small chamber for small CI engine.

Rolling the deck will not magically make the port better yes slightly better line of sight but you did not change short turn shape or length of it .

The best is to move the guides and do raised seat location = small chamber and longer sort turn.
