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.

You'll get an instant confirmation email with your part details and invoice. Orders ship from our Thousand Oaks shop or direct from the manufacturer's warehouse — whichever gets it to your door faster — so lead times vary by brand and part type. We'll send a tracking number the moment your parts move.
Made-to-order builds — carbon fiber bodywork, fabricated systems, custom finish work — run longer than off-the-shelf items because they're built per order. You'll get progress updates throughout the build.
Need a specific timeline on a part before you buy? Call 805-267-9762 or hit the chat — we'll confirm current availability and give you a straight answer.
