I plan on 185's unless I pull my current heads and identify obvious clearance issues---like flat-top pistons with little cut for valve clearance. Then I'd go with the 165's, but with the shorter intake runners (180 in current heads) is it possible that the change could actually create a performance drop? Are there sufficient gains with the AFR 165's heads in order to overcome the loses due to the shorter intake runners?

So, the first order of business is the wet/dry compression test, which I may try to squeeze into this weekend.

Question: I have a MSD mech-advance distributor. At cruising speed I think I can hear an intermittent miss. Each plug wire removal causes the expected sloppy rpm drop, so I don't suspect the wires. I suspect the magnetic module inside the distributor. What is the probability that the module has an intermittent electrical problem?
