Re: quick question ...max rev manifold?? (D-SPEED)

correct. the lines you are talking about are for heat expansion. the flange and the manifold itself are made of mild steel and stainless steel respectively. One "grows" at a faster rate than the other when heated. In order to not have flange sealing problems I would cut the reliefs, in fact I did on my own manifold, it can't really hurt.
