The LT1 6.2L direct injection engine is one of GM's latest offerings. Even in its infancy, LME is seeing impressive performance gains from its CNC ported cylinder heads, making these an ideal pick to make your Stingray a bit more venomous. ## 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 a rocker ratio to ensure accuracy. (example: .650" lift with 1.8 ratio intake and exhaust) *All Cylinder Heads Are Priced As ASSEMBLED Pairs FLOW NUMBERS WITH 4.125" BORE @ 28" WATER LIFT .100" .200" .300" .400" .500" .600" .700" VALVE SIZE INTAKE 75 146 226 292 330 346 359 2.125" EXHAUST 63 127 171 216 254 265 271 1.590" *Flowed with radius inlet intake/no pipe exhaust Intake Volume (cc) 320 Rocker Config.
