DECENT HEADER NEEDS IMPROVEMENT

September 08, 2013
I LIKE THE IDEAS BEHIND THE HEADER, BUT FOR DERBYING IT NEEDS SOME IMPROVEMENTS. THE MATERIAL USED WAS TO LIGHT, THIS IS FOR A DERBY CAR IT NEEDS TO BE ABLE TO TAKE A BEATING. I BOUGHT A SET AND RACED IN ONE CAR AND DRIVERS SIDE REAR PIPE BUMBED INTO THE BRAKE BOOSTER AND GOT ALMOST FLATTENED, BRAKE BOOSTER SHOWED A SCUFF MARK. THE HEADER NEEDS TO BE TUCKED IN TIGHTER TO THE HEAD AND VALVE COVER, THIS WOULD ALOW IT TO FIT ALOT MORE CARS WITHOUT DIFFICULTIES. THE NEED TO BE BOUT 4-6INCHES SHORTER ALSO FOR OTHER CLEARANCE ISSUES. AFTER SOME IMPROVEMENTS WOULD DEFFINETLY RECOMEND THIS PRODUCT FOR DERBYING.
Pros:
  • Nice looking
  • good craftsmanship
  • good sounding header
  • good exhaust flow
Cons:
  • to small guaged pipes
  • to wide to fit into a car that had a ford 460
  • in it factory
No, I would not recommend this product.

We have found that these demo derby headers will work with most tall valve covers. Speedway offer the following dimensions to help determine fit: Overall Height : 33.50 " Tube O.D. : 1.63 " Collector Diameter : 3.00 " Collector Length : 8.75 " Flange Style : Square Port Flange Thickness : .25 " Port Height : 1.50 " Port Width : 1.50 " Header Dimension A : 4.75 " Header Dimension B : 2.38 " Header Dimension C : 18.25 " Hardware Included : Yes Gasket(s) Included : Yes Material Type : Steel
