Valve Jobs and Other Head Work


We can open up your head! The stock 16v and 32v 928 head castings leave a lot of room for improvement in flow and turbulence. Carefully removing ridges and casting marks from within the intake and exhaust valve ports enhances flow and prevents pooling and fuel separation.

Improved throttle response and upper-end HP and torque are the benefits.

Send us your heads, we will open them to match the intake runners, remove the internal casting flanges and roughness, and given them and even, stippled finish within to keep the fuel in suspension and prevent pooling.

Porting and Finishing:
16v heads: $1,650 per pair
32v heads: $2,860 per pair

Multi-angle Valve jobs: (2-angle valve job on exhaust valves, 3-angles on intake valves)
16v heads $625 per pair
32v heads $870 per pair

Other charges may apply as needed, such as: valve stem replacement, head resurfacing, etc.

Valve job prices do not include parts. We will know what parts are needed after disassembly and inspection of your heads. Parts that may be needed include: valve guides, valves, springs and seats. Heads will be also be checked for flatness and decked if needed.
