This is the Holy Grail of all Cylinder Heads!

This Stage 4 head is the hallmark of our Performance Line of cylinder heads. It’s installed with super-strong Inconel intake and exhaust valves. Stainless steel Fire Rings are machined into the deck to prevent head gasket blow-out. This head can withstand extreme temperatures, pressure, and stress generated by high performance engines. It also comes fully loaded with all the essential components you need in an OE-quality cylinder head and costs up to 50% less. This Stage 4 cylinder head also has some serious improvements over the original OEM casting. It was crafted to create better coolant flow for more efficient heat transfer and contains higher nickel content for longer-lasting strength and durability.
