Overheating during cam break in

it never got quite up to 230 degrees, timing is set at 10 degrees advance at idle, according to the timing tab. didnt have a box fan that worked but i thought of that and will add that next. spark plugs didnt give any signs of extreme lean or rich conditions and they werent wet. they did not appear to have any traces of coolant. its been roughly 8 years since ive done a cam break in, maybe im just being paranoid and need to let er rip?
