LME CNC Ported LT4 Heads

LME ups the ante on the GM LT4 heads by running its CNC porting as well as guide and valve upgrades. Swapping out the factory guides and installing CHE Precision manganese bronze guides eliminates possible premature wear issues. With the new guides, GM titanium valves, and precision port work, these heads will be more than adequate at dealing with whatever punishment you may throw at your supercharged animal.

There are multiple methods of obtaining a set of LME CNC ported heads perfectly sculpted for your hot rod: 

Standard Core Exchange - We will swap out your useable cylinder heads with a freshly ported and prepaired set once we recieve them via your prefered shipping method or drop-off. Therefore, you will not be charged for the core exchange. 

Expedited Core Exchange - We will ship you a set of CNC ported heads fresh out of the machine and set up to your cam specs once the order is placed. Once your usable cores have made their way to us, LME will refund the cost of the cores. 

Current GM LT4 Cylinder Head core value is $1,900.00 

**No matter what method you choose, once order is placed, LME will contact you to ensure the best option is used for you or your shop. We will cover any details and clearify any question or concerns you may have. We will also seek out all possible information of the build to better provide the best service and parts for your project. This expedited service allows you or your installation shop to have all the parts in hand to complete a CNC ported head install without the down time and hassle of waiting on ported heads to arrive.

## By specifying your cam lift LME will assemble your cylinder heads with the proper spring installed height. This will result in optimal spring pressures and coil bind distance for maximum performance. Please include rocker ratio to ensure accuracy. (example:  .650" lift with 1.8 ratio intake and exhaust)
