was wondering what exhaust gasket set to use for my headers (rk sport). since the heads are d-port and the headers round, what has everyone here been using? since head will be ported, just wondering what part to get. trying to get the last few pieces together for my advanced induction head/cam swap!!
thanks guys

 

Many people have used the Fel-Pro 1406s on the RK Sport headers and reported good results. I'm using them on my long tubes and they have never created any issues.
