I ran one of the first sets that came out, on my then Coupe. And yes they did have a problem. I am talking 4-5 years ago. The car began to smoke quite a bit especially at idle. I had to R&I the heads myself, they were shipped back and repaired at no cost. If you purchased these within the last couple of years they should be fine. Have you done a leak down test?
