    MAP Stage 5 4G63 Cylinder Head Preparation

    The MAP Stage 5 service improves upon our stage 3 cylinder head in several ways. We take the porting and polishing to another level through aggressive intake and exhaust work including our proprietary MAP “B” shaped exhaust port, improved bowl to seat blending including reshaping of the guide bosses, extensive reshaping and finishing of the combustion chambers, and unshrouding of the valves for improved flow. Proven to 1000+whp in 4g63 applications on both of our in house race cars we feel this is the best performing cylinder head on the market, period.

    DSM cores are hard to come by these days, so you'll need to send in a good one to have the work performed on. The shipping address is on the form.

    Valvetrain Components

    We understand that customers looking for cylinder head service may have already obtained some, if not all, of their valvetrain components. We also understand that many customers are looking to purchase a complete cylinder head package from one reliable source. As such, we will provide the option to purchase valvetrain components to be included with your cylinder head service as seen below. If you already have the component in question and plan to send it in for your cylinder head service, simply choose "Customer Supplied."

    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 that 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.
