M54 Ported Race Head - Used

Fully Built & Ported BMW M54B25 Cylinder Head – Race Spec
 
Used, As is – Proven GLTC Head
 
This cylinder head was built specifically for and used on our M54B25 race car, which reliably revved to 8500 RPM using solid lifters and large camshafts (cams listed separately). Also works on M54b30 engines. Despite being paired with a DCT—which absorbs a noticeable amount of power—this setup produced 225 wheel horsepower, demonstrating the head’s airflow and efficiency.
 
The head is aggressively ported and configured to make maximum naturally aspirated power. All valvetrain components are high-quality Supertech parts chosen for sustained high-RPM race use.
