I always use silver mica capacitors in a pi network.  They cost more but I have never had a problem when using them.

It was just trial and error. I realized that I had to spread windings over the whole core. So I decided to remove one turn. I did it with L2 and L3 and have good results now. I stopped at this point and did not change anything else.

What I realized in the thermal images is that the 390pF capacitors heat up.
