Adz, i have a set of the new gaskets from Mike at ferriday and they look fab but havn't put them on yet.
The guy is very clever and is up for any advise anybody may need.
I use slightly thinner copper gaskets than shaun at the moment but they work really well.
If you need any allen headed bolts 10 by 1.25 thread ( about 60 mm long) for the manifold feel free to have six f.o.c from me mate.
