Will these fit my factory valve cover studs?

These are direct replacements designed to thread onto standard valve cover studs. Confirm your stud diameter before ordering — most domestic engines use the same thread pitch, but metric engines may differ.

Do I need to prep or paint these before installation?

No prep needed. They ship ready to install with the red finish applied. If you want a different color, light sanding and spray paint will adhere to the cast surface.

What quantity comes in this set?

Confirm the piece count for your engine configuration — inline fours typically use four caps, V8s use eight. Check the exact quantity listed for your order before checkout.
