Before you dial
Four questions our fitment desk handles every hour.
These are the calls that come in before the order. Read once, save yourself a callback.
- What info should I have ready before I call for a fitment check?
-
Year, make, model, sub-model, and current engine combination — including any non-stock displacement, cam specs, cylinder heads, and intended use (street strip, bracket race, Pro-Touring, daily). If you've already pulled the factory manifolds, have those off and the spark plugs out before you dial. A 90-second call beats a 90-minute email thread.
- Which engine and vehicle applications are in stock right now?
-
1,860+ SKUs covering 1964–2024 American V8 platforms: small-block and big-block Chevy, Ford Windsor and Modular, Mopar Gen III Hemi, and most late-model LS / LT applications. The fitment hotline pulls live inventory from the same warehouse system your order ships from — if it's on the line, it's on the shelf.
- What are the lead times on non-stocked or custom header orders?
-
Custom mandrel-bent and hand-ported orders run 3–5 business weeks depending on tube diameter, collector style, and coating. Tri-Y and block-hugging designs land in the middle of that range. We will give you a firm ship date on the first call — not a "we'll let you know" runaround.
- What's your returns policy on uninstalled header sets?
-
Uninstalled, un-modified headers in original packaging return within 90 days for a full refund minus outbound freight. Custom orders are non-returnable — but if our fitment tech told you it fit and it doesn't, we make it right at our cost. That's been the policy since 1982.
Still weighing torque curves, tube diameter, or coating options? The Find My Headers tool steps you through fitment by vehicle before you call.
