The BRODIX Spec. heads are made for tracks wanting cylinder heads that are cost effective and
equal for all competitors. These cylinder heads are very durable and user-friendly. Replaceable
phosphorous bronze guides are installed along with ductile iron seats. The Spec. head is 100%
CNC machined. Do not cut spring seats any larger or deeper than 1.550. Contact your local
association for exact rules. Please advise BRODIX of your track affiliation.
