Ok guys I finally got this head back on the bench to flow the exhaust after what I call shaping work. As I told you guys before I was told by a head guru (Darren Morgan) that speed on the exhaust side was more important than flow so who am I to argue. (Target as close to 325 as I can get) Again I am super impressed by this exhaust port and how quiet it is so I said to myself let’s not get stupid so I stuck with the valve job as it came from Speedmaster. A 60 degree cut and a 45 seat. Airspeed before after just chamber work maxed out at 270 (very nice number). Tonight after porting max airspeed was 332 FPS. DAMN!!!!
