Last summer I had fitted a 2.2 SC cylinder head on my 2000SC block. All seemed fine in fact she went really well however I have developed a noise. I have covered about 800 miles.Always hard to explain a noise, however best described as exhaust sound, but the exhaust is fine with no leaks. If I bring the revs up it virtually goes away. It is coming from the the 2nd cylinder away from the bulk head. If a remove HT lead the noise stops....However looking on this forum it seems folk believe a 2.2 head won’t work on a 2l block. (Wish I had looked last here last summer ) I feel as though I may be best to get my old head re built etc and fitted back on it’s original block. However before I spend the money I would appreciate the wise thoughts of the clever people on this site. Thanks in advance.
