Hemi Style Race Head for 212 Predators and GX200 Engines

• Fully-ported and bead blasted (option to delete)
• Milled to increase compression
• Oversize lightweight stainless valves, 28mm Intake, 25mm Exhaust (Choice of +.070 or +.230" longer)
• Aluminum retainers and split keepers with stainless steel valves
• 3-angle valve job
• Lash caps
• Choice of rocker arms
• Choice of single or dual springs
  

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.
