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.
## 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)
