We offer the full line of Noss Machine heads. These Billet Aluminum Yamaha Banshee Heads are easier to install than most other heads. They use the stock studs so no stud changing is required. Coolant deflectors are machined into the heads resulting in even lower engine operating temperatures and even cooling. Heads are compatible with Pro Designtm Cool Head domes. Domes come in 22-17cc. Custom domes are available.

                 Heads are available in 4 colors:


                           

Price list:

Silver head with domes  $260

Anodized colors (blue, black and red) with domes  $275

Approximate Cranking Compression

These pressures are estimates based on fresh stock bore, piston, porting, and deck height.

It is recommended to check your compression after installation.
