    FAQ

    1. Is anything else required to run these heads?

    No. Buying complete heads gives you a ready to bolt on product. These heads require the use of ARP head studs with 12 point nuts. We include the nuts and washers with purchase of the heads but you will have to purchase head studs if you do not have them already.

     

    2. How much power will I make?

    Depends on your build. The highest HP M90 vehicles and the fastest FWD GP on the planet currently run these heads.

     

    3. Can they be ported for additional gains?

    Yes but not like an iron head. They are already seat blended, have the short turn worked by hand and are cast to flow as a ported head out of the box. When doing so we recommend a matched lower intake. Expect gains of 2-5% with additional port work depending on if you have a custom intake manifold matched.

     

    4. Is there any special setup?

    Pushrod length should be checked and matched to your setup.

     

    5. What rockers can I use?

    Any rockers that work with normal 3800 iron heads.
