These heads will have a good wet-flow chamber design for more complete burning and lots of air speed in the ports. These Ported Iron Ram heads are an excellent choice for larger cams with .550" lift, either flat tappet or solid roller. Need 600HP with an iron head?
These are brand new heads, not reconditioned. They are considered heavy duty because they have pressed-in, hardened exhaust seats like diesel, and R/T heads. OEM Magnum heads are extremely prone to cracking between the seats. This is a very common problem with heads that have induction hardened exhaust seats, like the OEM iron heads. Our Iron Ram Magnum Heads #4666 have all of the bolt and accessory mounting holes and are a direct replacement for the OEM 5.2L/5.9L Magnum heads. These heads have all the original type and sized parts.
Keep in mind that these heads can be drilled to accept the "LA" style intake bolt pattern for an additional $80.
There is a great article on these heads in our tech section.
When using these heads with a flat tappet cam it will require that the pushrod tunnels be clearanced. We can do this for an additional charge of $40. If you need this done please make a note in the comment section when you place your order and we wil contact you.
