Making a exact clone with WinUAE

[kickstart]

Im trying to make a exact clone of my main amiga on WinUAE, a1200 060 50Mhz 32Mt, it will never be an exact clone but want it in CPU power and AGA, now i have in WinUAE a 060 21Mhz or 412Mhz with the Blizzard 1260 rom, how can i make a 060 50Mhz?

Thanks.

I play with the options of CPU and FPU but only with the "Aproximate A500/A1200 or cycle exact", the "Cycle exact CPU Emulation Speed" options are turned off and cant select anything.

I have selected in CPU 68060, More Compatible, Unimplemented CPU emu. ON FPU, CPU Internal, Unimplemented FPU emu.

Thanks!
