  • 4-valve per cylinder LSx heads from Arao Engineering!

    Got an email notice about this and thought I'd share it. Expensive at $7k but if you are going all out looks like they would be worth it. Anyway, the rest of us poor folk can still bench race with them, lol.

      $7000 for cylinder heads!?!? amazing or not thats rediculous. I think people are nuts for spending $1000 on porting. Good lord, you can build two forged strokers for that if you do the deals right.

        If you are going ALL out I can see it but a set of ported/polished Patriot heads on a forged bottom end is nothing to turn your nose up at.

          Not trying to sell of justify them guys. just thought I'd make people aware of them. I agree that for a street vehicle or weekend racer they are ridiculous. However, for someone running on a big budget needing to make all the power they can they may very well be worth it.

                      the transfer and rocker arm setup on those look just like the 3 valve heads GM is working on. The Price isnt too bad, we charge about $9000 for a billet engine block.

                          I dont think anyone has ever been able to get one of these conversions to run right...plus the fact that 4 valve heads are kinda pointless without DOHC...more bling than anything. I think a set of ls7 heads would do just as well

                            I disagree with that. Even though these would be operating off one cam still it's opening 2 valves on the intake and 2 on the exhaust letting in more airflow than any 2 valve arrangement will more than likely because it utilizes the entire chamber area more effectively than a 2 valve head can. It's doing the same thing overhead cams would just using rocker arms and push rods instead to actuate the valves.
