Are you tired of leaking and hard to install valve covers? Try MST - Engineered to Fit - Designed to Please.

MST CNC Machined Billet Valve Covers offer an ingenious no-slip inner lip to keep the gasket securely in place. The set includes smooth O-ring seals for the bolts, mounting hardware, and OE cork gaskets. The MST logo is CNC machined across the face.

MST Valve Covers also feature a Breather Port, pre-drilled and threaded to accept a 3/8” NPT fitting and features a re-enforced inside wall to give maximum thread grip for your fittings. Two plugs and two brass fittings are included.

Available from CB in Black, Blue, Silver and Red anodized finishes - Choose color from drop-down menu above.

Installation Notes:
- MST Valve Covers are based off of a stock-head design, and DO NOT fit CB's Comp Eliminator or Street Eliminator Cylinder Heads.
- Will not fit CB's 044 Cylinder Heads without additional machining to the 044 heads' Stock Valve Cover Rail.
- Not compatible with 1:4 Ratio Rockers without being clearanced. Confirm clearance with all Ratio Rockers before use - DAMAGE may occur if not clearanced properly.
