300pm vs 250 xb

[Varmint]

Is there much to gain with c10 vs c11 head swap ? Believe 67cc vs 61 cc, i mean 250xb is dang near close to output of 300pm. I know with 225 efi's the HP parts wake em up. But i have all the 300 ecu's here, just wondering if i should use em on my 250 or leave it alone already 125-130 psi all6
