Just looked up NGK, the ones mentioned above.

And they also have Iridium, (advantage? Worth the extra $$??)

Iridium BR6FIX 2318 0.04

Standard BR6FS

P.S. My engine is a 1990, and a bit low on compression, and top speed and slow putting around are important to me,

I have had good luck with NGK, BR6FS will work fine, don't waste your money for iridium's.
