Acymner Cylinder Head Stand - Heavy-Duty Engine Head Holder with Tapered Mandrels & Retaining Pins

The Acymner Cylinder Head Stand is a durable engine head holder that secures cylinder heads and blocks for cleaning, inspection, and light machining work.

This heavy-duty head stand is made to hold cylinder heads and engine blocks steady while you perform tasks such as cleaning, gasket replacement, crack inspection, and minor rework. Built with tapered mandrels and thick steel pins, the stand improves access and visibility so you can work safely and accurately without improvising supports.

How does the stand keep cylinder heads stable during work?

The stand uses a pair of 9.3 x 2" rods each fitted with an 8.2" tapered mandrel to center and support the head. Thick 0.63" retaining pins and threaded fasteners lock components in place so parts don’t shift while you clean or inspect surfaces.

• Tapered mandrels center the head and provide gradual seating.
• 0.63" steel pins resist bending under heavy components.
• Threaded fasteners clamp the assembly securely for steady work.

What sizes and clearances does the holder accommodate?

The set offers long mandrels and a separate, wider bracket to fit many common cylinder head shapes and larger heads used on trucks or SUVs. The design prioritizes clearance so you can access combustion surfaces, bolt holes, and gasket mating areas without obstruction.

• 9.3 x 2" rods with 8.2" conical mandrels for deep seating.
• Separate wider bracket option for large or wide heads.
• Open frame provides visibility around bolt patterns and mating surfaces.

How simple is setup and use for routine maintenance tasks?

Installation is straightforward: slide the mandrel into the head or block, align the bolt holes with the bracket, then tighten the fasteners and insert the pins. Once clamped, the head remains stable for cleaning, gasket re-lays, crack checking, or light machining prep.

• Quick mandrel insertion and alignment procedure.
• Fastener tightening locks the head in position quickly.
• Easy pin installation for repeatable, reliable holding.

Which projects and vehicles is this stand best suited for?

This stand is a general-purpose tool for car and SUV owners, hobbyists, and light-shop mechanics who service a range of cylinder heads. It’s intended for tasks such as cleaning, surface checks, bolt-hole inspection, and preparatory work before reassembly.

• Suitable for most common passenger vehicle cylinder heads.
• Works well for SUV and light truck heads when using the wider bracket.
• Helpful for crack detection, cleaning, and pre-assembly checks.

Who is this for? The Acymner Cylinder Head Stand is made for DIY enthusiasts, small repair shops, and anyone who needs a reliable way to secure cylinder heads and blocks for maintenance or inspection. If you regularly remove heads for gasket service, cleaning, or visual inspections and want a safer, more repeatable method to hold parts while you work, this stand delivers the support and access you need without complex fixturing.
