Engine Block Decking

At Northwest Motor Machine, we offer precision engine block decking to ensure your block’s surface is perfectly flat, true, and ready for a reliable seal. Decking is a vital step in any rebuild, correcting warpage, damage, or uneven surfaces that can lead to head gasket failure or compression loss.

Using high-accuracy milling equipment, we resurface engine blocks to exact specifications, achieving the ideal finish for modern gasket materials and high-performance builds alike. Whether you’re restoring an old motor or preparing a race engine, our attention to detail ensures a perfect mating surface every time.
