Hate to bring up an old thread, but I've got a question. Would a 1.8 header fit our 1.6 ecotec?

from my research it should. but it is possible it is the same part, i do not have a cross reference catalog anymore.
I checked out bad news racing's sonic header n they said no. It would suck to gamble with a $600 header. Right now i sent gasket pics with a tape measure for reference to john ashley of the UK. The $270 aint bad im just worried about shipping. I let y'all know what he says about the z 16 xer headers
