JEGS Tech Tip:
When installing embossed copper exhaust gaskets, which side goes toward the head? The flat side of the embossed copper exhaust gasket faces the head. The embossing allows for any irregularities in the manifold or header.
The Ultimate Gasket for Exhaust Sealing
JEGS Copper Exhaust Gaskets are made from 0.043 in. thick material with an embossed sealing area to provide a tight, leakproof seal even on irregular surfaces. Because solid copper, gaskets won't shrink, corrode, or prematurely wear, which prevents exhaust leaks & loose header bolts.
