Stage 5 Ecoboost Cylinder Head Service

With our Stage 5 Ecoboost 2.3 Mustang cylinder head service, we take porting and polishing to another level through aggressive intake and exhaust work including our proprietary MAP widened & resized exhaust ports, improved bowl to seat blending including reshaping of the guide bosses. We take it a step further with extensive reshaping and finishing of the combustion chambers, and unshrouding of the valves for improved flow.

Over the years, we've learned what makes a cylinder head flow better, and we've taken that knowledge, put it towards our Ecoboost 2.3 Mustang cylinder head service, and aimed to achieve what we feel is the best combination of parts along with the ideal porting / polishing to set and hold the current world record for overall horsepower on the 2.3L Ecoboost engine platform.

Why Choose MAP Machining Services?

We utilize a Serdi seat and guide machine that provides us with some of the industry's finest valve jobs. We not only cut seats for the non performance market, but have also designed specific cutters that we use in all our modern 4 valve heads. Every head is also vacuum checked after each seat is cut to ensure that no head leaves with a poor sealing valve. We would then typically set and adjust the installed valve tip height to our specs to ensure proper valve train geometry is maintained.

We also have a resurfacing machine that provides a superior RA, or finish, on both cast and aluminum blocks and heads, which is crucial for proper head gasket sealing in modern engines. Ours uses the CBN cutters and provides a superior finish to the older, multi-cutter systems that many shops still use.

Please Note: This product is built to order. Based on fluctuations in demand build times may vary throughout the year. Please contact an MAP sales representative for current estimations.
