S\/B Chevy engines with \"Vortec-style\" manifolds. They feature an LT1-style raised runner intake port design for increased air-flow and ultimate performance. A unique combustion chamber design positions the spark plug closer to the center of the cylinder, promoting a more efficient combustion resulting in more power. This head includes an adjustable rocker stud and guide plate set-up for use with adjustable rockers or washers to properly position the stud height to accommodate factory style self-aligning rocker arms. They have 20% more exhaust flow than a cast iron Vortec head, great performance up to 6000 rpm and can produce 9.5:1 compression with stock pistons in 350 cubic-inch engines.
