Those Toyota ports look great. I've seen a lot of super nice CNC work over the years. MCH always had nice stuff, Chapman had great stuff, etc.

I've had a fair amount of CNC heads on the dyno and lots of them run really strong. Some CNC work is so good when it comes off the machine you really don't want to touch it. Someone with a hand grinder is as likely to mess it up as they are to improve it.
