State of the art cylinder head for tractor pulling.
Performance
Years of research has produced high airflow combined with impressive wet flow for improved horsepower that shows up on the dyno.
Durability
Tired of valve train problems? Sophisticated valve train modeling and advanced geometry are two of the reasons why we have over 20 heads in use with valve train issues.
Each billet head is CNC machined from a solid piece of aircraft grade aluminum for the ultimate reliability, incredible performance and the lowest possible weight. Each cylinder head is sold in a kit which includes all of the items carefully designed to install the cylinder head on your block. This head package will put you in the winners circle!
Summary:
Airflow: over 500 cfm
Weight: 102 lbs
Down Nozzles: two per cylinder
Material: Billet (solid block) of Aircraft grade Aluminum
Oiling system: built in to the valve cover
Full Specifications:
- Port design by Dave Bamber – best airflow in pushrod tractor head to date at over 500 cfm. High airflow combined with wet flow testing and design has produced very impressive performance! Customers have been impressed with the performance over a wide rpm range and a wide range of fuel mixtures.
- Designed for maximum reliability, and light weight (102 lbs). The aluminum alloy and heat treat have been carefully selected for maximum heat transfer, strength, and crack resistance. In addition, the design has been optimized to eliminate hot spots which eventually lead to soft spots and/or cracking.
- Two fuel down nozzle connections are provided in the head for each cylinder. The location and orientation were carefully selected to optimize wet flow. Most intake manifolds are built with an additional port in each intake runner for the idle circuit.
- The oiling system built into the billet valve cover is simply connected by an o-ringed connection when the valve cover is bolted down! No need to disconnect / re-connect oil lines. In addition, the perimeter of the valve cover is sealed with an o-ring rather than a gasket. Similarly, the intake flanges are sealed to the cylinder head with o-rings.
