Details

The Edelbrock #60975 E-Tec cylinder head is replacements for 302, 327, 350 & 400 c.i.d. 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 cylinder 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. RPM E-Tec head is dual-drilled and will accept 1987-95 center bolt and/or 1986 & prior perimeter flange mount valve covers and most stock exhaust manifolds. E-Tec 170 head is 50-state street legal.
