Advanced Induction is getting 40+rwhp out of their stock 241 port, with stock valves. I've confirmed these gains.

If you do decide to try and port your own heads I have pics of a cut down head to show the intake runner, water jackets and exhaust runner. Print them out and to size and use them so you don't break through to any water jackets.
