Missed on this combo?
The RHS heads also have the standard/W2 exh pattern. Just like that picture the center two port were the most off. Had to trim the stock gasket, and grind slight on the header weld. I noticed this problem when i pull the eng back out for a freeze plug leaking problem.
Back on the track it didn't change the ET or mph. so it might not change much. my port is a standard port and them are a w2 port,might make a difference.
