You want more in your LS powered car or truck?  Did you just buy a junkyard LS engine that you want to put some Turbos on or some Nitrous?   You want a proven package to give you that power on the street?  Now you can have a proven power by the guys that have been making engine combinations run for 30 years. The VEPR (Velocity Enhanced Port Range) by Straub Technologies is designed to maximize the CSA in a cylinder head for the street car using pump gas.  This maximizes airflow in the low to mid lift range to bring power on for a wide rpm band.  This broad power is not sensitive to gear ratio’s like packages that make peaky power.  This broad power range makes the gear work and in turn the car accelerates down the road stop light to stop light. The VEPR packages from Straub Tech are available using GM OEM Cores that are hand selected or an import casting that we have worked with for many years supplying to other mfgs.  Each casting is fulling machined in house using state of the art 5 AXIS CNC porting.  All port designs are developed in house by Scott Foxwell, one of the top cylinder head porters in the country.  His attention to port velocity in cylinder heads will give you the power to put to the ground. This package comes with New LS1 Import Heads. 

Package comes with: Assembled CNC Ported Cylinder Head Fully CNC Ported with Chambers      Stainless Valves, PAC Springs, Steel Retainers, Forged Locks, Viton Seals Cam Change Gasket Kit OEM Head Bolts Choice of Custom Straub NA/NOS Cam, Turbo Cam, Blower Camshaft Delphi Lifters Delphi Lifter Guides LS Design with Bolts Straub Trunnion Kit with Bolts Straub Custom length Pushrods
