Big Block Road Race Header - WTB
I need some advice for big block headers on a lowered car. I would like 2" or 2 1/8" primarys, undercar or sidepipes. I have been running Sanderson BB5 block huggers but even my BFH cannot make them fit my new rasied port heads. The Stahl side pipe headers appear to place the collector under the frame rail so they might be more appropriate for drag racing. I think Hooker has a set of side pipes headers with long primarys for raised port heads. Does anybody have experience with them or can recommend an alternative? Good ground clearance is important.

Thorley has 2" primary/3.5 collector undercar headers for big block cars. I have had no trouble (car uses lowered VB suspension components), but do not know if they will work with raised port heads.

I put Hooker sidemounts with 2 1/8" primaries on my ZZ/502 with D-port aluminum heads. The flanges had to be ground on the underside to clear head bolts, but they fit other than that. No ground clearance problems........
