CHEV 350 SBC Cylinder Head

 CHEV 350 SBC Cyliner Head 

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 CNC flow numbers and flow over 250cfm on the 183cc and over 280cfm on the 200cc. 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.
