*840 kits in the past have had compression issues so we redesigned this kit to fix that. Pistons use pump or race gas. This is a bolt on kit with no machining required and it will work with stock or modified heads.

Please check your order thoroughly when you receive it and contact us if you have any issues at all. Thanks!!
