Thanks..at least someone is reading this...will try the link you sent
Merc uses the Delco R41T's on their 525SC (7.4 supercharged) package. I would think the R41T's or slightly warmer R42T's will work fine.
Gap is dependent on your ignitions ability. Most ignitions - if engine is tuned right - should be fine with normal .035" gap.
