Yeah, I've heard folks running the IRs. I've just never heard of folks going wrong withe the NGK 6ESs or NGK 7ESs. IMO, if the forumla works well, why change it? Different brands have already been tried on this old 4g63 motor and everytime, folks go back to the tried and true NGKs like the stock replacements or the one step colder (for those that need it).
