Model number on that Weil McLain is...? And fuel type?
Heat loads in basements are pretty tiny, especially if insulated the basement properly (?) as part of finishing it off.
When you have a boiler serving a tiny heat load you often have to up-size the radiation to keep it from short-cycling the boiler, but given the MA prices for natural gas vs. electricity it's still worth it to go with the hydronic solution.
But let's have the particulars first.
Boiler model/make size
Insulation & window details on the basement to estimate the load.
