Thanks for the info, yeah i was confused about the different types of exhaust manifolds. Got it figured outDon't quite understand what the op wants to do. He says "62T motor", so assuming he has a 62T cylinder, he would also need to match/enlarge the 61x manifold (using a 62T exhaust gasket as a template), then installing M8 Helicoil inserts in the 62T cyl. Picture is of such an install (after a few years)View attachment 330289
