Our stage 1 cnc program is built using our latest valve job and port design for the 5.3L GM cylinder head castings. This head is very popular with 4.8 and 5.3 builds and recommended for the stock 3.800 bore engines. Intake runner is redesigned and the 1.89″ valve is replaced with a 2.00 intake valve while the stock 1.55 exhaust valve is reused. this head makes great power N/A and also works well with boost.
