INSTALLATION NOTES

1. If this spring cup kit is used on cylinder heads manufactured prior to the introduction of

spring cups, machining to enlarge the diameter of the spring pockets will be required to
install these valve spring seat cups. A minimum valve spring counterbore diameter of

1.73” will be required.

2. The valve spring cups require the removal of the valve stem seals to be installed. We

recommend replacing the old valve seals with new valve seals. New valve seals should be
installed with engine oil applied to valve stem sealing area of the seal.

3. Valve spring installed height should be checked before the final installation of the valve spring

cups. If the installed height of the valve spring needs to be decreased a valve spring shim may
be installed between the spring cup and the cylinder head.

• PLEASE complete and mail your warranty card. Be sure to write the model number of this product
in the “Part #_______” space.
