I am extremely pumped up about this! We are making a fixture this week to unshroud the valves, CNC flowport from the seat to as far as we can in the chamber, CNC portmatch to our gasket lineup, CNC flowport from intake to valve bowl and CNC flowport from Dogleg to valve bowl. We will also be enlarging the drainback holes and milling and retapping the stud bosses. This will be one hell of a setup but I think we can get .290CFM + consistantly out of the intake @.600. This depends on the casting # but all indications look great here!



Very exited!

What else can we do to these heads?
