Do these headers require any prep or coating before installation?

Stainless steel doesn't rust, so no primer or paint is needed. They ship ready to bolt on. If you want a ceramic or heat-resistant coating for aesthetics or additional thermal management, that's a separate choice—these arrive bare and functional.

What hardware is needed to mount these?

Headers ship as an assembly. You'll need to verify your engine's factory bolt pattern and have the correct fasteners on hand—most SBC applications use standard header bolts. Check your service manual or have your block inspected before ordering to confirm exact mounting specs.

Will these fit my specific engine year and block type?

These are rated for small block Chevrolet engines across the 70–96 window, but SBC variations exist. Confirm your exact engine code and block type with us or your builder before purchase to ensure proper fitment—don't assume year alone.
