A pair of our Iron Ram cylinder heads with the "LA" intake bolt pattern. These heads are brand new castings with bronze valve guides. All of our assembled EQ (Iron Ram) heads now have bronze guide liners to prevent the common problem of valves sticking in the guides. BEWARE of purchasing these heads from anywhere that does not install the bronze guides! They have received our CNC Super Prep porting work, the guides have been honed and then they are given our proprietary valve job using new one-piece stainless steel valves (2.02" intakes and 1.620" exhaust).
 Our Iron Ram heads feature pressed-in hardened seats and modern port design to enhance airflow.

The photo below shows our CNC Super Prepped chamber (Street/Strip) Chamber with the racing valve job.

The photo below shows our deep port match work.

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. If you need this done please add it to your cart below in "Related Parts".

This head can be ordered with dual intake bolt patterns ("LA" & Magnum).
