Edelbrock E-Tec Cylinder Heads are replacements for 302, 327, 350 \u0026amp; 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 20% more exhaust flow than cast iron Vortec heads, great performance up to 6000 rpm and can produce 9.5:1 compression with stock pistons in 350 cubic-inch engines.

These changes were made to improve the limitations encountered in the stock cylinder heads when increasing the performance level of the engine. Changes include a 2.20+?G?-? diameter intake valve with a canted configuration similar to what is utilized in the GM LT1 Gen V engine. The intake valve change along with the unique port shape produce almost 400cfm peak flow.

Chrysler LA engines. They feature fully CNC ported 58cc combustion chambers and have an intake port volume of 225cc. These cylinder heads are an in-line valve design incorporating a 16° valve angle (stock is 18°) for improved air flow and increased power levels over heavily ported stock versions. They also feature the Chrysler W5 bolt pattern and have raised exhaust ports. The intake port has also been raised approximately 3\/4\" and the flange has also been extended to accommodate a stock (race) intake manifold such as our Super Victor #2815. Finally, a 5.56\" overall length valve (+0.600\" from stock) and raised rocker cover permit larger port cross-sections than in the stock head. Four versions are available; bare, bare with valves, complete (for hydraulic\/flat tappet cams and solid roller cams) and Pro Port Raw. End-seal spacers are provided. ** These heads require the use of a 14mm x 3\/4\" reach, flat gasket spark plug with a heat range appropriate to your application.
