Thats right guys, my head gasket for my 1990 16v has given up on me!

I'm thinking its time to get a new car tbh but thought i'd ask for some advice before i started doing anything.
Would anyone be interested in buying my car with head gasket gone or do you think i'd get more selling it for spares? its got the half leather ralllye interior which i hear can fetch quite a bit, ronal turbo r10 alloys in reasonable condition, and a milltek exhaust.
am i best just pulling these off then scrapping the car? it has had accident damage in past so dont think i'd be able to get much for it.
I got quoted £600 for the head gasket with it being a valver.
Any advice here would be much appreciated.
cheers guys
