seirra gasket set?

[paxtonr/t2000]

Can anyone help me tell which kit I need to order? I have a 1987 regal sebring with a mercruiser 175 4.3l 2bbl. serial number is b649560. sierra has 2 kits listed.

sierra 18-1275 head gasket set
chevy v-6 229/3.8l and 4.3

sierra 18-1278 head gasket set
chevy 262/4.3l 1 peice rear main seal and 262/4.3l gen II.

I dont need the valve stem seals but the intake gasket numbers are different. anyone know which one I should order? both are on iboats valve grind kits.

your 0B649560 serial number should have a one piece rear main seal
