Plan the repair around your valvetrain

Flat tappet conversion

The 2019–2024 flat tappet conversion kit uses matched camshaft, tappet, pushrod and rocker components. Read the kit contents, oil requirements, lash settings and installation instructions before ordering. If the cylinder head or block has been surfaced, contact us to verify fitment.

Gaskets for top-end work

The 2019–2024 top end gasket kit includes the head gasket, manifold gaskets, valve stem seals and injector seals, along with the other sealing parts listed on its page. A standard-thickness head gasket is also listed separately. Check the required thickness and the scope of your repair before choosing.

Confirm the supporting parts

Spring requirements, pushrod length and rocker compatibility depend on the selected camshaft and valvetrain. Use the instructions for the exact product rather than assuming every part in this engine category works in every combination.

Contact Hamilton Cams with your model year, engine configuration, current valvetrain, machining history and intended use. The conversion-kit page also lists qualified installers if you need installation help.
