Thanks all.
I'm definitely going the '.7 or .8mm' route. This is certainly not too tight on my engine with new crank/rods pistons etc. It was just that the squish that I have is so large.
I've ordered some thinner base gaskets from Marketplace and will do some experimenting when they arrive.
If I still can't get below 1mm then I think that I'll have to have the heads skimmed...there is a small lip on both heads to allow for this without having to go into the combustion areas.
