GM L92 Stage 2 Heads, Assembled

West Coast's Stage 2 CNC ported L92 heads have powered many engine builds ranging from mild street driven 6.0l to supercharged and turbocharged 427ci setups.  They can tailor valve train layouts from mild hydraulic roller cams to wild mechanical rollers utilizing large diameter dual springs and shaft rocker systems. Thier CAD generated port and chamber designs deliver high flow rates up to .650" lift while maintaining a safe port wall thickness.
