As it happens I replaced the manifold gasket about 6 months ago when it was fine anyway (the fuel filter turned out to be the problem) but I am worried that as a nut and spacer have fallen off one side this has allowed the gasket to break apart and I will have to do it all again. In the case of me having to do that I would like to know whether a fibre gasket or a steel gasket is better. The gasket I used last time was fibre and it is now obviously blowing as a result of losing a spacer (I think). The reason I think it is blowing is because in this pic you can see some coal around the manifold (circled):

I was hoping a steel gasket would be more robust and able to hold boost better (when I can finally start tuning again). Also what grade of sandpaper should I use for cleaning the flanges and the block surface? Last time I used 80 grit which I think was a bit too severe but it was all I had available. I was thinking maybe 280 or something?
