At the core of our engine-building program, we are fully dedicated to doing our best and protecting our reputation. We use only the highest-quality components and specialized machining and assembly techniques, ensuring they perform well and last long. Our goal is to create top-notch engines that exceed expectations and last for a long time.

The cylinder heads have been resurfaced, the lash adjustment has been set and a valve job has been done. Additionally, new valve guides and valve stems have been added for enhanced durability and performance. The heads are installed with new head gaskets and seals, torqued to factory specifications, and meticulously inspected.

Warranty

M45 Automotive's warranty covers against defects in our workmanship and product for 24 Months or 24,000 Miles (which ever comes first) from the date of receipt.

Core Charge

Unlike traditional practices, we do not require an up-front core charge when you purchase our product. Instead, we offer a convenient and hassle-free process for returning your cylinder heads, ensuring a smooth transaction for both parties.

By making a purchase from us, you agree to promptly deliver your core (cylinder heads) within 30 days from the date of purchase. It is crucial to adhere to this time frame to avoid any inconveniences. After the 30-day period, failure to return your core will result in the voiding of your warranty and a charge of $1000.

We pride ourselves on our commitment to customer satisfaction and understand that cores may have various issues. Rest assured, we accept your core regardless of its condition, as long as it matches the exact specifications of our head and includes all the parts that originally came with it.

Our streamlined core return process ensures that you can enjoy the benefits of your purchase while fulfilling your responsibility to return the core in a timely manner. We appreciate your cooperation in helping us maintain the quality of our products and guaranteeing a positive experience for all our valued customers.
