    I just picked up a used set of World S/R heads for my truck. Can anyone here tell me if they are 67cc or 76cc by the following info???

    On head under valve cover area:

    Right side of the head - S/R 1-052
    Middle of head - 91 NH
    Left side of head - W 11R

    I contacted World and they were no help and told me to take them to a machine shop and have them CC'd.

    Can anyone help?????

    So much for customer appreciation. Even if you did buy them used.

    Of course I could only ask questions via email, no phone to phone discussion. He was nice, just not real knowledgeable. Here's a couple photos.....



    Any clue?????

    The set I used to have were 76cc, 1.94/1.50. World is right though, have them CC'd or buy a buret and do it yourself.

    There should be some numbers on each end of the head that has an ID part number that World can cross and tell what you have.

    They look like open (76 cc) chambers to me.

    I have a set that came on my Camaro. I pulled a valve cover and took down the numbers. I called World to see if they could tell me if I had 202 160 or 194 150 valves and what size cc heads. They told me the PN#s were all the same and I would have to pull a head to find out :-(

    I could not believe that they did not have different casting numbers to denote the specs of the head. But according to the person I talked to there via telephone they don not.

    At least your heads are off and you can find out easily. I am not going to know what I have until I pull the engine down.

    They are a pretty good budget head, IMO!

    I'm pretty sure that the cc will be stamped into the end of the head- not just a part number but an actual 76 or 67 hanging out by itself.

    There's no way that any mass manufacturing company would ever stampe every single head they make with the same number. How would they know which one to pull off the shelf and ship to a customer?
