Description

These heads are designed for entry-level street performance engines and ideal for operating in the idle to 6500 rpm range. Made from A356 aluminium castings, these complete heads include larger-than-stock 1.43" (36.3mm) dual valve springs to handle up to 0.575" (14.61mm) maximum valve lift. They produce  over  280cfm. The combination of a 5-angle competition valve job, diamond-honed bronze guides, hand bowl blending, and professional assembly means these heads outperform some of the best brands in the business. Recommended spark plugs are 14mm x 3/4" reach with flat gasket seat.
