LS4 King is excited to offer these multi piece LS header flanges for all LS based engine applications. These flanges are cut from .375" T304 Stainless. They feature ports optimized for 2" OD primaries. 

Each package contains 4 flanges; 2 per cylinder head.

These are the same flanges we use in-house on our own header and log manifolds. We've found that the multi piece construction resists warpage and leads to less broken manifold bolts over time.
