High-Tech, Lightweight, and Ready to Take on the World Photo Gallery
The heads used on this new 482 are absolutely identical to the set used on the 440 turbo Rodney and Travis built a couple of years back. They are off-the-shelf Butler Performance Group Edelbrock "Wide Ports" that use Ferrea valves. Comp Cams titanium 10-degree retainers and chrome-moly locks hold the Comp Cams 946 series valve springs. They develop 315 pounds of pressure at the seat and 850 pounds open.
