I know for sure my Group A gasket must be on borrowed time with over 440bhp so time has come to look at the top end and make it strong.

Can these multi layer gaskets be thrown straight on, without skimming as currently fine, standard head bolts.

Or do you have to have block decked and head skimmed?

Which one???? not just for who it's made by but cost, layer etc

Genuine mountune 4 layer

or

5 layer cometic
