Is that the smallest port that will be produced??? I'd rather see a 210-215cc port if possible for us stock displacement guys looking to put down 450 ft/lbs of torque.
If you are really like that, I don't see how you can stand to ever buy a computer, hell bigger and better changes on them every 5 minutes...
Subscribing ! Just read this thread . it is really neat to see development like this from a sponsor . Would like to see more information as it comes available as in performance
characteristics and pricing . What blocks have been used in the research and development ?

The runner volume doesn't mean squat compared to the cross-sectional area and shape of the runner. Guys, it could have a rolled valve angle which would extend the runner length and increase volume, even without increasing the cross sectional area. I for one and happy to see a larger, high flow cathedral port head come on to the scene.
The market is already crowded with excellent small runner, high flow heads, but most of the high flow large runner heads (that work better with 400+ inch motors) are fairly expensive. If PRC can bring an affordable head that can feed a stroker motor, I say go for it!

Guys settle down a little bit, we'll have smaller runners to go along with the bigger runner stuff. I'm just messing with big ports right now

I would love to swap out my patriot 5.3l heads for a better flowing head with a little more compression. Hurry up and finish them already. 
And if you want to use my car as a test feel free. Already got 470rwhp with your MS4 cam on a mustang dyno.
