Head Work for your 16 Valve Porsche® 928<

Porting - Polishing - Milling - 3 angle Valve Job

We can open up your head! The stock 16v 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 Polishing:
16v heads: $1,450 per pair

Multi-angle Valve jobs:
(2-angle valve job on exhaust valves, 3-angles on intake valves)
16v heads $425 per pair

Other charges may apply as needed, such as: valve stem replacement, head resurfacing, etc. Prices do not include parts.
