E-TEC 200 Aluminum Cylinder Heads
This Cylinder Head features a fully polished exterior finish for show stopping looks!
Edelbrock E-Tec heads are 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. These heads include 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 over 35% more exhaust flow than cast iron Vortec heads. These heads outflow other aluminum heads of a similar design by 10% on the intake and 17% on the exhaust, making power up to 6500 rpm. The 64cc chambers produce 10.2:1 compression with flat-top pistons in 350 cubic-inch engines. RPM E-Tec heads are dual-drilled and will accept 1987-95 centerbolt and/or 1986 & prior perimeter flange mount valve covers and most stock exhaust manifolds.
Installation Note: To use stock rockers on S/B Chevy heads, .100'' longer than stock pushrods are required. S/B Chevy heads may not be used on engines with less than 4" bore (262, 265, 283, 305, 307 c.i.d.) except with cams having less than .450'' valve lift. Requires hardened pushrods. Recommend Edelbrock 350-9629 for flat tappet cams only
Tech Tip: To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs such as the RC12YC. They are 0.230'' shorter than a conventional spark plug and have a 5/8'' hex for easier access.

Specifications:
Will the edelbrock valve covers part # 4263 work with these heada part #60985?
The installation note says to use a .100 longer pushrod for stock rockers. If I'm using comp cams retro fit lifter that use a 7.266 pushrod, 249-7809-1, and jegs 1.5 roller rockers do I need a longer pushrod for these heads?
