Comp Cams or Mopar Perf Timing Chain??

Always a good idea to get all the bolts started first, then you can tighten them a little at a time. For the front cover its not very important as other can be. No sealer that I know of that would make easier. Sounds like a good plan. IIRC there might have been a kit YEARS ago that cam with the little ends and the rubber front section.
