S55 Stage 2 Performance Cylinder Head

The S55 can suffers from valves floating at high boost levels so we've selected a high seat pressure Supertech spring package to go with our stage 2 cylinder head that will allow for good sealing at very high boost pressures.

Our Stage 2 Cylinder Heads feature the following:

• Supertech Valve Spring Kit - 82lbs of Seat Pressure
• Ferrea Valve Spring Kit
• Complete Disassembly & Cleaning
• Comprehensive Leak, Crack & Pressure Test
• Inspect All Components For Irregular Wear
• Our High performance Five Angle Valve Job
• New Valve Seals
• New Valve Guides
• Trueness Checked & Resurfaced Mating Surface

Please remove camshafts and eccentric shafts from cylinder head before shipping. We can remove and reinstall these components for you at an additional cost of $500. Shipping cost may also need to be adjusted due to the increased size and weight.

• A Core cylinder head is required for all head work, please call or email if you will not be supplying us with a head for updated core market price.
