Frequently Asked Questions
Will this manifold bolt directly to my big-block without modification?
Port location and bolt hole spacing depend on your specific engine block. Verify port centers and mounting points against your engine before ordering—you may need minor machine work for a perfect fit.
Do I need to use high-temp sealant or gaskets when installing this?
Yes. Stainless steel expands and contracts differently than cast iron, so quality header gaskets and high-temperature RTV are essential to prevent exhaust leaks.
Can I paint this or should I keep it bare stainless?
Bare stainless will weather naturally to a dark silver-gray patina under heat. If you want color, use high-temp ceramic or metallic paint rated for turbo manifold temperatures—prep the surface with fine abrasive and primer-rated for stainless.
