12496821 This aluminum small-block Vortec manifold was designed for maximum horsepower with throttle body fuel injection and EGR usage. The manifold will fit all Vortec design cylinder heads (P/N 12529093, 12558060, 12497186, and 12464298). Technical Notes: To use EGR, the gasses must be plumbed from the exhaust manifold into the intake manifold. Many exhaust manifolds have drilled and tapped holes that can be used to fabricate a tube. An example is the 1996 and later pickup truck with RPO L31 350 engine, which uses exhaust manifold P/N 12557828, EGR pipe P/N 10220275, and fitting P/N 12552329. That combination will fit this manifold for late model pickup trucks. Vacuum controlled EGR valve P/N 17113457 can be used on some models.

Note: 2.5F & 4.5R" tall
