Good To Know

Q: Will these covers clear a roller rocker setup? A: The tall finned profile can add clearance, but check your specific rocker and stud heights before ordering. A test fit is the safest way to confirm.

Q: Do they come with gaskets and bolts? A: Check the listing contents for included hardware. Gaskets and bolts are often sold separately for valve cover sets.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
