Problem: After pulling my '74 SB's 1600 DP engine for manifold work (I've almost got that damned heat riser cleaned out), I noticed that the spark plug in cylinder #3 is seated into the head cockeyed. Apparently someone before me (honest . . . It wasn't me, I just got this car) must have inadvertently screwed it in at a slight angle. The weird part about this is that the engine seems to run just fine with it in that way. Anything I should watch out for? Is it safe to continue to run the engine with the plug in this way? What kind of repair ($) would I be looking at to get it corrected, or is junking the head for a new one my only real option?
