I am looking for a good head for my Audi 80 block that I am fitting in my Rabbit GTi. I have heard that the G60 is heat treated and stronger than the normally aspirated 8v head. Is this true? Do they flow better? Will it fit on an Audi 3A 2.0l block? Will it fit on a 1.8l block? If so, is there any real benefit to using one? Will I need to mill it down to boost the compression ratio up to 9.5 or 10:1? Any help here is greatly appreciated. I am new to VWvortex, and apologize if this is on old hack question that has been answered many times. If it is, how to I find the old archieved topics.
Thanks
-David

Re: G60 head on a 2.0L Audi 3A block?? (racerxsf)

they flow just as poorly as any 8v digifant head. The heat treating is good for boost, wont melt the exhaust valves so easily.
for the most part, they SUCK unless ported.

yes, and sodium filled exhaust valves. no. yes. yes. not really. It will still be 10.5:1 with this head.

Re: G60 head on a 2.0L Audi 3A block?? (vwpat)

Thanks for the help. It sounds like they are basically compatable with the same flow characteristics (generally poor- needing porting), but are stronger with more heat resistant valves. What about fuel delivery. I thought that some of the G60 heads were CIS-E? I am hoping to use the stock CIS system if I can...trying to keep it simple.
Also, any feelings on whether to use a g60 8v head versus some other 8v head like solid lifter vs. hydrolic?

Re: G60 head on a 2.0L Audi 3A block?? (vwpat)

Again, thanks for the advice. What I understand is rebuilding any 8v head (G60, Solid Lifter, Hydralic) for a 2.0l block will work without any real preference to one over the other... except that the German built heads might flow a bit better. However, the G60 head would be the one to get only if the future of my project had any sort of forced induction going on due to its increased strength for the higher heat...no real advantage for normal aspirated engines.
Thanks:
