Hot off the presses. All I can do is show pictures, I trust Nick is doing the right things. I did provide him with pictures of a sectioned head and he did mention before he started about sonic checking the thickness of the port walls. I told him if he wanted to do any fancy tricks like angle milling, etc, I was okay with it, especially since he has the intake too. I'm looking forward to seeing if he doesn't anything different with the chamber shape than I did (other than higher quality work).
