Chevy Camaro 305 Cylinder Head & Camshaft Install - My Generation Camaro, Part IV Photo Gallery
The S/R Torquer 305 heads come with a 58cc chamber and quality Manley 1.94/1.50-inch stainless steel valves. Tim put a 30-degree back-cut on the intake valves to improve low-lift flow. He also lapped the valves to ensure a solid valve seal. The intake-seat width is 0.060 inch with the exhaust at 0.100 inch.
