I also wanted to add getting good low lift flow #s 265 @500 is fairly easy with little work on the short turn.After 500 or right when ,and it will #s will fall off by 20-30.The talent of porting the d port is getting that 265 back and biting at the str to extend that to 300 or 325.I wonder if he is using or any other porter of these heads a 2.19 valve?Cast heads are tough, messy,hazardous to the lungs,kills burrs,takes time and porters don't get paid enough
