If you're looking to rebuild your old Chevy LS 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 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.
