| What larger valves will work well in a farm stock WC with a WD45 crankshaft and flat top pistons? |

| I do not know... but for your rpm and displacement,will bigger valves make a difference? I got the impresson that port and manifold work were more important,but I have been wrong before. |

You are correct. Port and polishing will give you an improvement and without it larger valves will not do much. The porting will come first in any case.
