I used those for the OFNA RTR engine, and its noticeably cooler that the stock head( it was sold and it makes me turn the engine leaner until it broke the conrod). bling factor, cooling factor is great, but its always good to have the STOCK cooling head since its a part of the design of a specific engine. I guess.
and yet you don't want your engine that cold.

I got tired of seeing my 2.5Tmaxx running 290-295F here in the summer when its 95F outside - this is with good smoke, it just run hot. I put a Nov2 head on and temps dropped to 250-255F. Don't think that's 40%, but it is 40F. Nova makes a real nice looking head.

Not sure where your running at but here in the South..Louisiana/Mississippi when it's 95 or 100deg and heat index is 110 w/o wind there is a definate need for them. I have seen other racers use them with good results.

If you do run a large cooling head be sure not to lean it out too much

you say you dont want to run the engine that cool, but cant you lean it out more and still run at 210 250 ish? it should still have plenty of lubricant because its not hot enough to burn it all off? just my thoughts. if im wrong let me know. im still pretty new at this.

A lot of guys dont tune to temp anymore that the old school way. But you dont want you mill to get so hot that it burn off all the oil and yes Riverdriver in the south where were both from it does get very hot in the summer and the heads do help.

+1...Its all about the smoke, and the performance..but we do still check temps..its a real good way to assure your tune is good..It has nothing to do with how you tune, but it will tell you if you are off tune to a certain degree, and if you need any aftermarket cooling head..you are doing something wrong

Absolutely, I tune for performance with plenty of smoke but always religously keep a temp gun in the pits!
