These heads feature full CNC porting, EV-8 stainless steel 2.020", 2.050", or 2.080" intake / 1.600" exhaust valves with 11/32" stems, magnesium-bronze guides, super-clean chrome-silicon dual valve springs, premium chromoly retainers and locks, and a race-radius valve job. Additionally, they feature larger spring pockets for aggressive cam combinations and a wider variety of springs. This LS-Series is the perfect choice for your next late-model Small Block Chevy build.
