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 Polishing: 16v heads: $539 per pair 32v heads: $895 per pair Multi-angle Valve jobs: (2-angle valve job on exhaust valves, 3-angles on intake valves) 16v heads $260 per pair 32v heads $485 per pair Send ½ with your heads, pay us the balance COD upon completion. Other charges may apply as needed, such as: valve stem replacement, head resurfacing, etc. Prices do not include parts.
