Vortec L31

For being a relatively new cylinder head it is gaining popularity rather quickly due to its outstanding performance for the price of reconditioned heads. However they do require a vortec compatible intake manifold. Excellent choice for a daily driven street car. Can be machined for 2.02/1.6 valves..
