ITs a stock casting but with extensive hand port work larger valves heavier springs, etc. I have a set of these and they flow even better than MTI qoutes at least as far as my expience with. CNC porting is great but there are just somethings that a well expiernced hand porter can do that a CNC machine can't. I have a few pictures if you are interested

I am very pleased with my hand ported heads from mti. They flow like crazy. I made more power than i expected like 382ls1.422 hp with the c1 and bolt ons. These heads just went down in price too... damit!! Their cams are good too. I would go with the c2 or x1 if i did it all over again... Just buy them and you'll see the 03 cobras way in the rear view....
