LME PORTED GM LS3 Heads

Many hours of R&D have gone into the development of this powerful LS3 CNC program. With stout flow numbers and an efficient port shape, the LME CNC ported LS3 offering is truly bolt on performance.

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 LS3 Cylinder Head core value is $495.00 

**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.

Parts: Reuse GM Intake valves, REV Stainless Severe Duty Exhaust Valves, LME .660" Lift Spring Kit w/ Titanium Retainers.

## 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)
