Introduced in 2004, the LE-200’s have become the benchmark for superior high-end performance Type 4 engines. So named because they represent the Leading Edge of technology and the intake ports flowed 200CFM @ .500” valve lift, a value they exceeded by the 2nd version. The exhaust ports average flow is 75-77% of the average intake port flow, making the LE-200’s an excellent choice for track cars.




ALL CYLINDER HEADS ARE SPECIAL ORDER AND MUST BE ORDERED SEPARATELY AND PAID FOR WHEN ORDERED. All cylinder heads are sold only in pairs. PLEASE ALLOW 4 WEEKS TO CREATE YOUR CYLINDER HEADS.

Details

The design philosophy for these heads was simple; achieve the maximum possible performance from readily available castings while maximizing flow utilizing valve sizes that we know are controllable with high quality, off the shelf valve train components. This approach keeps the cost associated with high-output, high RPM, reliable cylinder heads as low as possible.

While many products for engines are developed, brought to market and never further developed, that is not the case with the LE-200’s. As of 2012, we are on the 4th version of the LE-200. To say that they have changed radically from inception to present would be a misrepresentation. The initial offering came forward after much development and accumulated knowledge. They were fantastic heads right from the beginning. But we didn’t stop there. We have continued to improve these heads along the way whenever new data or new components have made improvements possible. Port flow has inched upward, but the most notable improvement is the addition of premium Crower springs & chromoly retainers. We were happy with the springs we started production with, but when Crower introduced this spring, I jumped at the chance to incorporate it into the line-up. The dimensions allow for a much more positive location of the base eliminating any chance of spring migration, and the improved material composition greatly extends spring life in high revving competition vehicles that see elevated oil temps.

The LE-200’s are the obvious choice for large engines that need to make torque at the highest possible rpm. That said, for the adventurous, they can be used to build a screaming smaller displacement engine.

The LE-200’s are the finest high-end performance Type 4 heads on the market today because they are the gathering point for all of our accumulated knowledge and the best parts available. That approach will never change, meaning whenever you decide to purchase a pair, you can be assured of receiving a pair of heads in a class all their own, combining exquisite machine work complemented with top of the line components.
