I'm putting a set of 440-1 Indy heads on mine that I ported. Getting some real nice numbers already but I may go ahead and upgrade them to a 2.250 valve since I have them sitting here.

1970 Duster
Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
9.42@138.27

Livin and lovin life one day at a time
