Product Details

This high-performance cylinder head features fully CNC-machined intake ports, combustion chambers, and exhaust ports for optimized airflow and power delivery.

Key Features:

  • Fully CNC-ported intake ports, exhaust ports, and combustion chambers for maximum flow efficiency
  • Dyno-proven performance: 457 horsepower and 438 ft-lbs of torque
  • High-quality conical beehive valve springs with steel retainers and locks
  • Supports valve lift up to .600 inches for aggressive camshaft profiles
  • Compatible with Edelbrock LS series intake manifolds and camshafts
  • 50-state street legal (CARB compliant)
  • Requires rocker bolt kit #8597 (shorter bolts prevent protrusion into intake ports)

Ideal for street performance, hot rod, and muscle car builds seeking reliable, emissions-compliant power increases.

Easy ordering process

Easy to use site, worked great

GOOD

Found the product via a link in a message board. Looking into the problem of SMOD experienced by Xterras. Found your site to be cheaper than Amazon, though I may have received the shipping free from Prime. Either way, your site said it was compatible with my truck, Amazon said it wasn't. I'm going with the people who deal less with books and cheap Chinese knockoffs.

Love the low prices

Had part in stock. Ordering was easy.

Easy Affordable

Thanks for the easy order.
