The BRODIX 18 C cylinder head has an 18° valve angle that works well on dirt late model or serious drag racing applications. This head has special valve centerlines and dowel location requiring special components. Interlocking valve seats are installed along with replaceable phosphorous bronze guides. The combustion chambers may be angle milled down to the mid 40 cc range without weakening the deck surface. The 18 C has two exhaust bolt patterns available and a 5° intake face requiring a special intake manifold and components.
