|We've developed a CNC porting program for the new Edelbrock 348/409 cylinder head. Our CNC porting and 5 angle valve job pushes these heads into the 330-340cfm range @ .700" lift on the intake and 250-260cfm @ .700" lift on the exhaust with big gains throughout the entire lift range. Send us your heads and we can apply our CNC porting and valve job work for $1000.00 surfaced and assembled ready to bolt on (any parts needed are extra). We can also supply complete heads from $1497.50 each, call or e-mail for more info at email@example.com
Dyno data coming soon comparing out of the box heads to our CNC ported heads!!!
