I have had similar happen to me. Once the heads have been surfaced in my case skimmed, the height had changed just a small amount from where it used to sit. Hence, the manifolds ended up being slightly out of alignment. Loosen or manipulate the manifold about and do as zorba suggests, a bit at a time. regards, sneezy --Previous Message-- : G'day Neil : I've not had this problem with the : rangies but have had it with the Mini's : I used to work on in my younger days - : sometimes extractors were just a tad : out. : What I did was start with the hole on : the extractor that doesn't line up : completely. With the manifold out from : the head as far as the length of the : bolt, start the bolt till it is in the : head by at least a couple of turns and : then progessively put in the other : bolts but again, only to a couple of : turns.
