Without knowing the exact pressures on the seats and open and coil bind clearances I wouldn't do any decision making either way
I don't remember the exact installed height for stock 360 heads but I do remember them being quite a bit shorter installed height than stock BB springs are
Don't take a chance until you get more information as far as how much pressure on the seat and opened
I use from 140 to 175 Lbs. on the seats on flat tappet cams and up to 375 lbs. open with as little as .060 from coil bind and shoot for no more than .100 from coil bind at max lift on any motor that will be shifted at or above 6000 RPM with out removing the inner springs, if yours has more pressure than that stated above I would remove them
