Send us your GM factory cores and allow us to sculpt our proven port configuration and build you a set-up that will dominate any street or track you choose to do battle on.

## 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 the rocker ratio to ensure accuracy. (example:  .650" lift with 1.8 ratio intake and exhaust)
