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.

Called MAPerformance and talked with a guy named Cody. Awesome dude. He wrote up an invoice for exactly what I needed. Quick and easy. He even went as far as asking the mechanics questions he didn't know himself to provide me with as much information as possible.
I went with the stage one as my head already had a pocket port and it more or less needed some love. Payed what I needed to and shipped it out under the guidance they provided as well as even a video on how to package the head.
I was given a 5 week lead time.
I got it in less then 3.
I will use them every single time I need a head rebuilt as they did better, faster then any shop local to me.
I have no testimony for how it runs as I own a DSM and it's never running. If your looking at this you know exactly what I mean.
