The cover sits flush and i even double check with feeler gauges to make 100%. Originally i set it up just with the shims that come with the kit ( one on both sizes of the cam adapter) and only needed 2 shims under the retainer plate aprox .058 worth, and the endplay turned out perfect. I did however put some extra shims later in between the cam adapter and block and got the gear to clear and everything set up fine but i worried about the cam being so far forward that the lobes aren't centered under the lifter bores, not WAY off but enough i can tell they arent centered and with the roller cam that kinda worries me. Trying to get ahold of jesel to see what they have to say, the entire motor is brand new so there has to be a way to make it work, just a little dumb on this i guess. Thanks for the advice though!
