LS3, LSA, and LS9 HEAD PORTING SERVICE
LS3, LSA, and LS9 HEAD PORTING SERVICE
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.
## 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)
*All Cylinder Heads Are Priced As ASSEMBLED Pairs
**CORE CHARGE WILL BE REFUNDED WHEN USEABLE CORES ARE RETURNED BY CUSTOMER
