Frequently Asked Questions
Is this head new or remanufactured?
New. It is a new casting assembled with new valvetrain components — not a rebuilt core.
Do I have to send back a core?
No. There is no core charge and nothing to return.
What else do I need to install it?
Plan on a new head gasket set and head bolts for the C13. They are not included. Message us and we will match the right kit to your engine serial number.
How do I confirm it fits my C13?
Send us your engine serial number (ESN) or the casting number from your old head. We verify fitment against 305-0617 before the head ships.
Is the C13 head the same as the C15 head?
No. The C13 and C15 use different cylinder heads. Send us your serial number if you are not sure which engine you have.
How long does delivery take?
Heads are crated and handed to the LTL carrier in 1–2 business days. Transit is typically 2–5 business days depending on your location.
