New S/B Mopar Aluminum Heads for Sale

Out of the box heads assembled by the manufacturer, regarding flow, I have not flowed the heads, my understanding is that a local head porter (SOCAL) has tested and gotten great results, also, Hughes Engines is testing the heads and will be selling shortly.

The heads are as represented, my suggestion to any purchaser is to have a qualified machine shop disassembled and check any heads purchased assembled by any manufacturer no matter.

My experience with these heads, port matching only, 418 stroker with hydraulic flat tappet 237/242 @ .050 547/555 hydraulic flat tappet dyno at Westech 476 HP 513 torque. A customer replace his J heads, got rid of detonation, chassis dyno @ JBA in San Diego made 380 HP at the rear, another customer in Canada changed heads, roller rockers and push rods drop a full second E.T.

These are great replacement heads for a street car, want to go racing buy another product
