Hughes sells a full CNC port Edelbrock RPM set for 3K, then recommends better exhaust valves and milling to correct chamber volume at extra cost. This gets you a 199cc intake port.

Which is why I couldn't understand all the howling when BPE priced his new 205cc heads at 2125 bare. To me that's a comparable head at a competitive price.

I paid 2595 to the door for my AirWolf 220s in 2013 with beehive springs, lock and retainers specified for a .625 lift fast rate of lift solid flat tappet cam. I went this route because it would allow me re-use my headers, 1.5 Crane gold rockers, intake, and valve covers. Then Brian talked me into selling my M-1 and buying an Edelbrock Super Victor, and letting him whittle on it. so like most projects like this, another 500 I wasn't counting on...
