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 finishes, 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.

Customer Reviews
I will always be getting all my parts from Maperformance no matter what they have what you need whe the Map spec cylinder head came in was package just as a head should be packaged. No damage at all and came with all the parts that I wanted and will do the job perfect. You guys got your stuff together and make sure no only the customers are 100% satisfied, but the engine work that you guys do is 1000% better then the local shops here in UT. Again I thank you guys Cody, charlie, Chris, and everyone else who has helped me.
Where do I start! Cody, the engine builders to the whole MAP team throughout the whole process went out of their way to answer every question I possibly had and streamlined the process from the moment the head left the door to MAP.
10/10 would recommend their service and top notch customer service. Cody is the man and provided an outstanding customer service and parts selection. Received the cylinder head within 2 weeks of sending it in.
This stage 1 prep is worth it. Mirror finish results, top quality parts of your choice for internals and best of all the quality of work performed to achieve what you want for a build. Might as well go all out! Just make sure you all follow up on how to properly package a cylinder head for shipping to make it easier for the guys at Maperformance.
I had MAP do this to my evo 9 head prior to rebuild and it worked flawlessly. Shipping container was pro and deck surface was mirror finish. You guys got your stuff together!
