Im getting ready to install my new Edelbrock E-Street heads and valvetrain on my freshly machined block. The heads,cam, springs, valves, lifters, and pushrods all came in a kit meant to work together, and I plan to reuse the factory rockers. The problem is that the block deck did have some machine work and now that I'm getting ready to install the heads and valve train I realized that the work on the block may effect things. I called the machine shop that did the work and they said that there wasn't much taken off the block and that everything should still work together, but I should still check to make sure. I,m just wondering what the easiest method for doing this is? Ive watched some videos and done some reading. At this point I figured that I would put everything together and try the marker on the valve stem trick and just see where everything is riding. Unless anyone has a better method.
