Default Picco P9R Cooling Head

So I'm putting a Picco P9R Evo-3 into my Kyosho GT2. Considering this engine was designed to run sticking out of the body, I'm a tad worried that the head is not going to be getting enough air flow to cool sufficiently.

I can't find anywhere that makes a larger cooling head for this engine. Would one from any other Picco work? Like one for a P3 .28? Or how about swapping on a Nova oversized cooling head? Or any companies that make one for the Picco engines?

I've done tons of searching on rctech and everywhere else I can think of. Any help is appreciated!

Get an offroad head if you want more cooling.

Any Picco (based) .21 engine using a same kind of buttonhead....

If you are talking about an Ofna Picco, then yes.

The newer Picco onroad engines have that head set-up where the button itself has some fins on it. Most of the older Picco offroad motors do NOT have that so I suspect they will not fit (though I could be wrong). The Boost line looks like it does have it though. So the one seen in the link below should fit and looks like it has an extra fin or two on it:

That engine will cool just fine under a GT body. I own and run
many different on-road .21 engines (Picco, Novarossi, MaxPower,
RB) with the smaller, lighter on-road cooling heads with no problems
in my 1/8 GT cars. If you're that concerned about engine cooling,
cut a hole in the winshield of the body directly in front of the engine
and cut another hole in the rear window directly behind the engine.
Unlike off-road truggys, the 1/8 GT cars get alot of airflow under
the bodies. Sometimes too much air, you'll find out find out when
you get that Picco broken in and get it up above 60 m.p.h..
It's quite a sight seeing a car that heavy, catching air at those speeds.
Takes off like a kite, does a few flips in mid-air and slides a hundred
feet across the tarmac on it's lid. ............ ......
