  • 2006+ vvt rockers on 3500 heads

    Hey all. Just did the lower intake on my wife's g6. 2009 with the vvt 3.5. The rockers seemed to be a lot lighter than the stock 3500 ones I'm running in my beretta. Has anyone tried to use the 3.5 vvt rockers on a 3500? I did a quick mock up on some heads I had around and it seemed that I would be able to use the newer rockers if I used the saddle and bolt from the 3500.. just wondering. Thanks.

    Hows the geometry look where the rocker touches the valve stem tip?

      It looked ok.. the heads I mocked up didn't have the valve springs installed but the valve stem seemed to line up just fine with the rocker tip. But I was in a rush to get her car back together so literally spent maybe 2 minutes doing that. The OAL eyeballed the same. The saddle is much shorter on the vvt but the 3500 saddle seemed to work.

          Went to the local pull a part in Indy and test fit the VVT 3.5 rockers (using 3500 saddle and bolt) on a stock 3500. Here are some pictures.

            When you use the 3500 saddle and bolt with the 3.5 VVT rocker the geometry looks and feels good to me. Correct me if I'm wrong. However, it appears that custom length pushrods will be required. The 3500 push rods are too short and the 3.5 VVT push rods are too long. I wish I had some feeler gauges with me and then I could let you know how much of a gap there was. I grabbed 12 of the 3.5 VVT rockers and brought them home with me. Not sure if I'll try to use them or just throw the stockers back on. I also brought home 1 of each push rod to use for mock up if you want some better pictures or such.

            What're your thoughts Ben? I'll put the rockers on a scale tonight or tomorrow to compare the weight. I'll also check the length.

              Made an article for the rocker arm options, and added 2 pics showing the contact patch of stock, and the gen 3/4 hybrid rocker.
