Briefly getting oils up 250-260 will not hurt anything either according to very knowledgeable people at Gibbs.

On my road race car (331 stroker,solid roller cam),I'd let it idle to warm up,idle rpm was set at 1,000rpms....once the water temp got in the 150+ range and oil temp was in the 125 or so range,I'd go to the end of the paddock and do figure 8's at about 2500 rpms to warm up the trans and rear diff. and also drag my left foot on the brake pedal to get some heat in the rotors and brake pads.......Once water and oil temps were in the 180 range, I'd go park it and get ready to go on track....when called to grid,I'd let it idle till water and oil temps were at 180 if possible before going on the track....
30 minute race in 100 degree heat of the summer would see my water temp at no more than 185,but my oil temp sometimes was as high as 260,mostly ran in the 230 to 240 range.....that engine ran 8 seasons like that with no apparent problems..........I was using Mobil 1 synthetic 15/50 oil....
On my street car engine (331 stroker,hydraulic roller cam), I will let it idle until the water temp is around 140 or so and the oil temp is just coming off the peg at 100 degrees,then drive it easy for a few minutes till water temp is at 180 and by then oil temp is around 140 or so....the oil temp will continue to come up with driving until it levels off around 180 to 190 with normal street driving.....
been doing this since the late 90's on this engine and it has just shy of 40,000 miles total........at least 200 drag strip passes, and 2,500+ miles on 4 different road courses......it's just starting to "use" about 1/2 quart of oil every 2,500 miles which is not bad considering how I have used and abused the engine.....using nothing but Shell Rotella T diesel oil in 15/40 weight....
