Chevy 350 Dart heads - Valve seal size?

My local auto parts place doesn't know...

These are the heads on my Chevy 350:
Dart #301-10021111
SB-Chevy Iron Eagle S/S Series Cylinder Head 165cc Intake Runner
72cc Combustion Chambers
2.02'' Int/1.60'' Exh Valves
1.250" Single Springs

My #5 cylinder is getting oil fouled on a regular basis. I've checked the compression and it's between 182 & 185 on all cylinders, so I"m guessing/hoping it's the valve seal. What size/type seals do I need for these heads?

Thank you, gentlemen, for your expertise!!

Sam
