The current Champion listings show an RH18Y rather than the old H14Y for a '64 259. Is anyone aware of any problem with this substitution?

Not really; if you experience pinging might want to try a colder heat range, but I have heard that you can't really compare heat ranges between old and new Champions anyway. The "R" is for "resistor" but that shouldn't be a problem.

I have run the recommended Champions for years (H10, H14Y, J12), but when I was having fouling problems from running rich in my '64 R-2 Avanti, Norris Edmonds gave me a set of Autolite 437s and they ran noticeably better than the J12s. I have since put them in my '64s and '53 Commander. I don't believe they are a resistor plug like the current recommended Champions. I have been told that since flooding doesn't happen in fuel-injected cars, modern plugs are not built to withstand flooding and are ruined by flooding. Paul Johnson

I've had good luck with Bosch Supers; I'll agree that the platinums are garbage though.
