One last thing for now and I think I got a really solid understanding... I drew a red outline and blue outline in this picture of one of the transfer ports. When I chamfer it to make it flow more towards the intake, am I taking off material from just the red section, or both the red and blue? The outlines aren't perfect dimensions, its just so you get what I'm trying to ask. Basically am I gonna dig into the actual port (blue) or just the "sleeve section" (red.)
