I'm sure I have a set, but I'm also sure they been sitting in my garage for a while, so I would suggest sending them out to be cleaned reguardless. I'll go see if I can find them, if so, $20.00 ea. + shipping. PM me if your interested.

I don't think that's the fix you are looking for. There will be extra fuel across the entire rpm range especially at idle. 550s aren't necessary on a stock n/a motor. What do you mean by going lean??
fix the problem, don't cover it up.

Personally I've had two rx7s (one s4 and one s5) with no emissions AND exhaust and they were fine... even with the 6 ports removed on the s5. You don't have the airflow to need 550s even in the secondaries. It's just not necessary. Fix the REASON you are going "lean".
BTW, have you taken an english class in your life? Punctuation and complete sentences man!!;)
