Long sitting 273, any ideas?

Hey all,

just picked up a 65 cuda with a 273 thats been sitting for nine years without turning over. I drained gas tank, changed oil, lubed cylinders, changed battery, used a little starter spray and she cranked to life after a few tries. I ended up changing the fuel filter three times since it kept getting clogged. the idle was rough at first but settled right out after about an hour. anything else i should do before running more (just concerning the motor)? i was thinking radiator flush, change the oil again after a few hours, and maybe even another fuel filter seeing as it kept getting gunked.

any ideas, suggestions etc would be of great help!

thanks
