EngineQuest (EQ), the leader in hard-to-find new and reclaimed engine parts, has introduced two new Vortec cylinder heads to upgrade ‘69-‘90 350 Chevy 5.7L engines. Given the proven performance of the EngineQuest (EQ) Chevy Vortec ‘96-‘02 head (EQ Part #CH350C), EQ has expanded this version to earlier 350 applications.
Made from the highest grade cast iron, the CH350E (EQ Part #CC170BA) replacement cylinder head comes with a heart-shaped 64cc Vortec style combustion chamber, a 170cc intake runner volume, ‘69-‘86 intake bolt pattern and features center bolt valve cover mounting holes. The CH350F (EQ Part #CC170BA2) has the same features as the CH350E but includes perimeter bolt valve cover mounting holes.
Both the CH350E/F Vortec cylinder heads allow engine builders to re-use existing, stock, chrome and cast aluminum intakes and valve covers while receiving the benefit of the latest chamber design for improved airflow.
Utilizing flow cast technology, these high performance cylinder heads improve on the original design with a thicker deck for added strength, Dura-Bond exhaust seats for greater resistance to cracking, and a redesigned water flow system for improved thermal conductivity. With CNC machined guides and seats, a superior port finish for increased flow and a three angle valve finish, EQ’s cylinder heads offer the best of both worlds – OE fit and improved performance.
To ensure the highest quality, EQ conducts a 25-point quality inspection on every new cylinder head shipped. EQ is the only head manufacturer that offers a one year parts and labor warranty on stock replacement applications.
