Core Options

Click here to download, print and fill out this form to include with your shipment if you are sending us your core for service.

We offer three different options in regards to our cylinder head core service, please select the one that fits your specific situation and time line.

Customer Supplied - Select this option if you have a core cylinder head to send to us and you would like us to perform the services to your cylinder head after it has been received.

MAP Supplied (NEW) - Select this option if you do not have a good cylinder head to send in as a core. We will purchase a new core to use for your cylinder head service.

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.

Flow Testing Results

We had the head flow tested and the results were impressive! It went from sub 200 CFM on the intake and exhaust side to 250 CFM through the intake and 225+ CFM on the exhaust. Those are impressive gains over stock!
