Steam radiator removal and system "on"

Options
Hi Everyone,
I have a quick question. I just disconnected 3 cast iron steam radiators (1 pipe system) by shutting off boiler; draining and disconnecting the radiators while also shutting the valves to each disconnected rad. This was done for new hardwood flooring installation. My question is: can I fill and run the boiler/ system as is without the 3 radiators to get some heat into the house as temps are getting into the teens the next few days? Will there be too much pressure on the closed valves? is it safe to run the system for 1-2 days as is?

    Will the radiators be at a different height than before? Many people come here, trying to figure out how to adapt their radiator piping 3/4".

    Just keep an eye on the disconnected radiator valves for any leakage.

    Thank you guys! Appreciate the info and quick response. Yes the rads will be 3/4" higher (luckily the pipes have some play in them up/down) and I'll keep an eye on the valves for any leakage until the floors are finished.
