Requires 5.34 to 5.44 for the .070" longer valves or 5.11 to 5.16 for the .230" pushrods (not included). Hemi heads are prone to piston-to-valve clearance. They must be checked carefully. They are also subject to coil bind using .070" valves. We do not recommend 1.3 rockers due to valve-to-piston clearance issues.

The .230" valves may create improper valve geometry when using 1.2 or 1.3 ratio rockers.

.274 and 1.2 rockers are the maximum recommended valve lift for .070" long valves.

*Note: Heads are typically built to order. Please allow approximately 1-5 days before shipping.
