Cometic head gaskets
Hi if H1247SP2043F is the part number for a 71mm bore does any one know the part number for a 72mm bore gasket? regards Terry

Almost. The last 3 digits are the thickness in thousandths of an inch and the F at the end means it's a fiber gasket. So 043F is 1mm (0.043") thick and 059F is 0.059" thick or 1.5mm in new money.
Always specify the finished bore size and the thickness. and always dry fit the gasket to be sure that the fire rings are concentric with the bores. Suzuki used to supply 75-76mm gaskets to get around the poor fit.
