Maximum competition, performance marine and high torque, 8,000+ RPM, 500+ cubic inches.

Dart 340/370cc oval port Aluminum cylinder heads have high velocity 340/370cc intake runners that produce incredible midrange torque and throttle response. Oval port heads really “wake up” a big block in marine applications, or in a heavy car with an automatic transmission. They also work great in a light car with a tight torque converter.

Dart big block heads deliver superior performance without the hassles of welding and modifying stock castings. We applied proven Pro Stock technology to produce big block heads that out perform the competition, yet Dart heads can be used with most off the shelf pistons, manifolds, headers, and valve train components.

Heads are sold individually.
