What head gasket shall i use??

Silver Zetec Turbo

Im using an RS multi layer gasket on a 2.1 bored out block . I hear that a lot of folks are using this type of gasket even on 1.8 litres

Crazycage- is that a steel gasket?

Johnny Knoxville

crazycage

Yes mate

TomPengelly

Can i still use this as ive gone slightly oversize bore size to fit this vw pistons, and the parts people say that the bore size on the blacktop gasket is smaller than the silvertop slightly..

Still ok to use the steel blacktop gasket?

Johnny Knoxville

Yes it will be fine up to 1.5mm over bore I was told.
