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 nonperformance 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.
