Porting DC Stage IV iron heads

I once asked Cody how many hours he thought we had in those 906 heads. That 1st set he estimated at 300 hours. It didn't take anything like that for the next set that went 336 cfm with smaller valves.

300hrs?
I don’t think I’ve ever spent even 1 tenth that amount of time porting one set of heads.

As I’ve said before........ I want the most gain....... for the beast work.

A decent set of FAST BBM heads would get about 20hrs of porting.
Then you still have all the other labor operations on top of that.
