1980 1.1 gg code exhaust manifold

Struggling to get an exhaust manifold for my little 1.1 anyone know if a 4-2-1 from a polo 86c will fit the head and the exhaust system? Any advice much appreciated many thanks

Yes that should fit. I had a 4-2-1 manifold on my 1.3 GF (basically the same engine) which also fitted polo's etc. is was an Ashley manifold

Brilliant cheers buddy got one on order to try out 

I'm looking at getting a better exhaust for my 1.1, how did you get on with the 421 manifold?
