What is the best way to install MACE MLS Exhaust Manifold Gaskets for HSV LS1, LS2, LS3, LS7, LS9, and LSA Supercharged 5.7L, 6.0L, 6.2L, and 7.0L V8 engines?

Before fitting the gaskets, ensure all mating surfaces are thoroughly cleaned using a non-abrasive Scotch-Brite pad. If sealing has previously been an issue, you may apply a light coat of copper spray to the gaskets prior to installation. When tightening the bolts, use the following torque sequence and specifications:

First Pass: 15 N·m (11 lb-ft)

Final Pass: 20 N·m (15 lb-ft)

Tightening Order: 6 → 3 → 1 → 2 → 4 → 5
