Another important thing to note is that these heads require certain components and others are highly recommended. These parts are listed below:
1. Required: Trick Flow Specialties Head Bolt Kit (TFS-92030) or Trick Flow Specialties Head Stud Kit (TFS-61404304)
2. Required: Harland Sharp Rocker Shaft System for Magnum applications. (S72025K or S72026K)
3. Recommended: Trick Flow Specialties Rocker Shaft Stud Kit (TFS-61400613)
4. Recommended: Harland Sharp Rocker Shaft System for LA applications. (S70025K or S70026K)
