I assume the intake runners match the ridges in the port floors. Can anyone school me on this theory? I assume it has to do with splitting the intake charge to minimize the obstruction of the valve stem and guide (?). I’ve never seen this before.
I'm with you on this one
is this the new modification being done to these heads now?
One of you should post these questions with that picture on SpeedTalk.com and see what you get for answers.
I guess I should check out SpeedTalk.com. Thanks for the tip, Brad.
If it is in fact to shape the charge past the guide boss & valve stem, it seems this mod would be more effective on the port roof than the floor. If the charge follows the port into the bowl, wouldn’t charge following the upper half of the port cross the guide boss & stem, while the floor charge would fall directly across the valve face (???).
