Upgrade your engine with Pacific Performance Engineering LB7 cast iron cylinder heads, eliminating head gasket and cracking concerns. Crafted from high-quality alloyed gray iron, these heads boast superior fatigue strength, heat resistance, and creep resistance, significantly extending their lifespan. Matching the stock cast iron cylinder block's heat expansion rate prevents blown head gaskets. The heads feature cast-in fuel injector cups, addressing OEM injector cup leaks. Each head includes new springs, retainers, locators, valves, seals, keepers, seats, guides, rocker arm dowels, and freeze plugs. Whether replacing damaged aluminum heads or seeking enhanced reliability, PPE LB7 heads are the optimal choice.
