Fitment & Product FAQ
Does the cylinder head come fully assembled?
Most of our cylinder heads are fully assembled with the camshaft, valves, valve springs and seals fitted, ready to install. A small number of heads are assembled but require you to reuse the camshaft and rockers from your original head. Check the 'What's Included' section on this page for your specific engine.
What's included in the box?
It depends on the product. Most cylinder head kits include the assembled head (with camshaft, valves, springs and seals fitted), a VRS head gasket set and new head bolts — everything needed for the job. Some heads require you to reuse the camshaft and rockers from your original. Where the engine uses an MLS head gasket, the thickest specification is supplied. Gasket-set-only products include the head gasket, manifold gaskets, valve stem seals, rocker cover gasket, head bolts and all O-rings. Always check the 'What's Included' section on this page for your specific product.
How long is the warranty?
All our cylinder heads come with a 12-month warranty covering manufacturing defects. We stand behind the quality of every head we sell.
Will this fit my vehicle?
Check the 'Fits' section on this page for compatible makes, models, years and engine codes. If you're unsure, contact us with your VIN and we'll confirm fitment before you order.
How long does delivery take?
We dispatch from Perth and Melbourne. Most orders arrive within 2–5 business days. Express shipping is available at checkout.
Do I need a machine shop before fitting?
No — our heads are precision-manufactured to OEM specifications and do not require machining before installation. They're ready to fit.
