Message	Charles heads have the following done. JWT Valve springs JWT R4 Cams Ferrea 1mm OS Valves Ferrea retainers Viton Seals OE Valve keepers My standard street port (283cfm at .400") Back cut 2nd angle on intake valves Coated Chambers Coated exhaust ports Honed valve guides Decked & fully deburred The heads are capable of 8500-9000RPM I also modified his lower plenum to uncover the injectors placement in the plenum. This attributes a better fuel mixture motion and atomization in the port. The intake ports were left with a fine carbide finish to add to the mixture motion process.
