Port my own heads?

Fully ported with no welding or epoxy on my bench I usually hit 297-299 at .700 and 230's on exhaust.
I've flowed some other "pro ported" heads that were supposed to go 300+ and never got to 290!!

These heads are hard to port though unless you've done them before. It's hard to manage air speed in them once you get everything "correct"!
