Eric I'm not sure about that but I'm guessing they are close. The question I have is to Darrenx33 how are you going to tilt the manifold to get the valve cover on. You will have to take the top of the manifold off to get to the bolts that are in the plemum and then loosen up all the bolts and break the intake gasket seal and take a chance of the intake leaking water or air. All that just to get the valve cover off. If you are using the factory steel shim head gaskets and its a new motor what are you going to do then about re torking the head bolts take the intake back off again? I can't believe that somone has a 69Z and isn't willing to buy a set of covers and send them to Jerry and let him reskin them so they look orig. At least they would have drippers on them . This setup done correctley is not a maintance nightmare. I bought my intake in 1971 and put it on my Z 7 years ago I've put over 16k and haven't turned a screw on it in over two years The only time the intake been back off is when the top of a valve got chipped from a bad rocker arm. Bottom line is you can't have the crossram WOW factor if you're not willing to give up something.
