thats worth a read.
its why i think the MD is good, alot of others are unverified, and it does seem to be that some are not what they advertise.
you may end up with a £100 aluminium gasket which does nothing.
these are researched, tried and tested.
for the sake of £80 it might be worth the punt to go the whole hog for the MD one.
just my 2p worth
