These aren’t your average headers. We engineered, welded, coated, and tested these to be the absolute best-fitting, longest-lasting, and most leak-free headers you can bolt onto your LS or Vortec Jeep conversion.

Kit Contents:

• Headers, left & right
• Header flange bolts, serrated
• Collector flange rings
• Collector flanges, V-band style
• Flange gaskets
• Clamps, V-band

Premium Materials & Craftsmanship

Each set starts with 304 stainless steel tubing, TIG-welded by skilled hands and joined to a 3/8” thick laser-cut flange for a perfect seal. These headers don’t warp, leak, or rust like mild steel imitations.

Perfect Fit for Jeep Conversions

Built specifically around Novak’s motor mounts, these headers clear steering shafts, frame rails, spark plug wires, and bellhousing areas. No hammering, no guessing—just a clean, confident fit.

Leak-Free V-Band Collector System

Forget the old 3-bolt flanges. Our V-band collector system locks the system together with zero leaks, zero alignment issues, and an easy service-friendly design.

• Includes both stainless and mild-steel flanges
• Heavy-duty V-band clamps
• Serrated flange bolts to resist loosening
• Premium graphite gaskets

Performance Merge Cone

Each header features a precision-formed scavenging cone at the collector to improve exhaust velocity and flow. Expect sharper throttle response, stronger midrange torque, and that crisp LS exhaust note you’ve been chasing.

MCX Ceramic Coating

We finish every header with our MCX aluminized ceramic coating—formulated for stainless steel. It looks incredible, protects the metal, and keeps heat under control.

• Reduces under-hood temps dramatically
• Rated to maintain its polished finish up to 1300°F
• Outlasts typical ceramic paints and coatings

Even after years of hard use, they’ll still perform and look like new.

California Compliance

These headers are not California CARB approved.

Engine Compatibility

Fits all GM Gen III & IV V8 engines — including LS1, LS2, LS3, LQ4, LQ9, LM7, and other LS/Vortec variants from 1997–up.

Note: If your heads have paired center ports, you likely have a Gen I/II small block and need these headers instead.

Vehicle Compatibility

Ideal for nearly all Jeep models running GM V8 conversions.

For XJ / MJ Cherokee owners, see our XJ/MJ specific headers.

Installation Made Simple

Install using the supplied graphite composite gaskets and serrated bolts. Choose your preferred downpipe material and weld to the included stainless or mild-steel V-band flanges.

The compact, block-hugging design allows three common routing options:

• Under the oil pan in front of the sump
• Under the bellhousing slope
• Behind the transfer case—exit driver or passenger side

If you encounter rare starter clearance issues, ask for starter motor #6494 at your local parts store.

The Novak Difference

We didn’t just make a header—we built a solution. A leak-free, power-boosting, perfectly-fitting system from the same team that engineered your mounts and adapters. If you’re trusting your Jeep’s heart to a GM V8, it deserves a header worthy of it.
