If you're looking to rebuild your old Big Block Chevy powerplant, you can't go wrong with a set of performance cylinder heads. TSP's heads are cast from premium aluminum for improved weight and heat management over the old iron. They are engineered and are not CNC-ported for maximum horsepower and torque.

This bare assembly is a great starting point for a performance engine build. It's designed for maximum flow and performance in the hands of a skilled builder or machine shop. It features a thick deck to help resist warping and comes with threaded bolt holes on the ends for an easy install.

TSP cylinder heads are sold individually as bare assemblies. To achieve maximum performance, it is recommended that a licensed engine builder or machine shop coordinate matching short block and engine internals.
