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.
