Description

Beehive Valve Spring Conversion Kit for GM Fast-Burn Cylinder Heads.

Convert the valvetrain on your aluminum Fast Burn heads to the beehive-type system used on Chevrolet Performance's latest Fast Burn heads (P/N 19300955) - and used on the ZZ5 and ZZ383 crate engines, and CT400 - to gain greater high-rpm capability and valvetrain stability. The springs, retainers and other hardware are direct replacements for the conventional springs and hardware, with no machining of the valve spring seat required. The engine's existing intake and exhaust valves are retained, allowing installation without cylinder head removal if compressed air or another method is used to hold the valves closed. The engine's existing rocker arms are also retained. The kit comes with components to convert a pair of cylinder heads.
