Take control of your LS engine’s cooling efficiency with the M&H Steam Port Vent Crossover & Delete Kit, crafted for a clean, reliable, and performance-focused solution across a wide range of Chev / Holden LS engines. Designed to suit LS1, LS2, LS3, LS6, LS7, LQ4, L92, L99, LM7, and LM4, this kit delivers the cooling stability your build needs— whether naturally aspirated, boosted, or track-driven.

Steam ports are critical for eliminating trapped air pockets that cause hot spots and detonation. This M&H kit ensures proper coolant flow and venting, helping maintain consistent cylinder head temperatures under heavy load, high RPM, and boosted conditions.

• Prevents hot spots and detonation
• Improves coolant circulation and engine reliability
• Clean, tidy installation with a premium finish
