Not that long ago,most big bhp people were using studded blocks ,

and grp A or the equivalent head gaskets.

Now it seems that you can only use a mountie gasket,not even a

co*etic one will do?

Is it still feasible to use a grpA gasket in this setup,or is it not worth the grief?

wrc is the best only if the two surfaces are perfect. if not the gpa is better

Could it take 500bhp?

Did the rs500 touring cars use this setup without coopers rings?

It could last with the block wire rung...i doubt very much it would last very long without though.

it has to be wire rung to make it last iirc.

coopers o ring does both and is not as sensative to the condition of the surface
