Wonder if you have to much airspeed over the short turn now, especially with the pushrod pinch opened up. I'd bet adding width to the short turn might help?
It would for sure. What I was hoping for was to see how close we could get to 285-290cfm with the least amount of work and cost for guys that can’t afford to pay for a full port job. Knowing what a 2.055 and 2.08 valve are capable of I can size the port accordingly. The shortside width and height is the biggest time factor on these heads. A 285-290cfm smooth flowing port would get most of our members the horsepower they are seeking. Doing it on a budget would be a bonus
