so i started off just wanting to put the headers and intake I had on and in the process an intake bolt on the very back driver side got broken. Long story short I took the heads off and replaced gaskets and when I got it all together and fired it up it smoked white and smelled sweet out of only the passenger side exhaust, so I took it back apart and installed another head gasket and the problem is still there. It's worth saying that before I took it apart the second time I chekhed the plugs and the number four plug was a little wet on the threads. Another thing was coolant was being overflowed out of the overflow so I think compression gases were pushing coolant out, haven't done anything after this second time any advice would help
