STRAUB TECHNOLOGIES VEPR CNC Ported & Assembled Cylinder Heads [260cc | 64cc | 2.165 | 1.6 | SQUARE] (GM 6.2L LS3)

The Straub LS VEPR head program uses NEW castings that we import from an overseas supplier that manufactures for several OEM's. Each casting is inspected and tested before machine work starts. Available in a LS Cathedral and LS3 Square port, we machine each and every casting in house on our state of the art Rottler 5 Axis machining center. Each head is CNC ported using our VEPR port design (Velocity Enhanced Port Range), that gives an engine maximum power over the broadest rpm range. Our competition valve job has been painstakingly developed by Scott Foxwell to enhance flow in the mid lift range. We offer a valve job for both NA engines and boosted engines to maximize longevity. We hone valve guides based on engine application and use of a power adder. All heads are assembled using our hand selected components that have been used in the industry for decades. Valve heights are held to a range of +.005" to ensure proper rocker arm adjustment and lifter pre-Load.

Note for Boosted applications our heads are cast with very thick decks which allows for better sealing under boosted applications. Components
All heads come with stainless steel valves. Heads for boosted applications come with Inconel exhaust for extreme heat. All retainers are steel. All valve locks are forged. All valve seals are metal clad viton. All spring bases are alloy steel. All springs are 1.290" Dual springs are good for up .670" lift.
