I bought a 426 street wedge engine a few years ago and just now working on it. Cam and lifters were already out of the block and in a separate box when I picked everything up. So I dont know which lifters go into which slot over the cam shaft. I've heard if you are re-using the parts then the lifters have to be placed over the same cam lobes or it will create problems. Is that a valid statement? None of the lifters appear to have unusual wear and none are concave.

Im not re-building for top performance, just want to complete a build that runs and operates before going after top end performance build. And my budget is restricting the quality of performance at the moment.
