I'd diagnose the no-start and timing belt first though before putting money into a radiator you won't need.
if the valves are bent you can buy used heads for $100-$200 and swap them out and be back on the road relatively inexpensively as well.
resurface the heads, new subaru headgaskets, new Subaru timing belt and lower cogged pulley and you're good for another 100k for $200 in new maintenance parts.
