I've experienced something sort of similar - very intermittent rough running, difficult to reproduce.
George Coy actually nailed it for us - induction leak. We'd checked all the intake tube fittings and they were tight and wouldn't explain why it was intermittent anyway.
So we went in again and started really looking. There was a crack around the weld where the 'quick drain' intake manifold kit was. Just inspecting wasn't enough, grabbing a hold of the Curtis valve and twisting it is what revealed the crack.
A word of caution that you're probably already aware of but adding detergents to an engine that is already sludged up (generally if it has been run for many hours on a non-detergent oil) could be asking for some tears. If it's been run on an ashless dispersant then can't see a great problem, except that a properly set up engine shouldn't require magic mystery oils. See BeechTalk for a more informed discussion on MMO et al.
