Unfortunatleythe only head wehavehad on our dyno is the Fireballed stage 2 head, this is what we using when we run the 13.09 @ 104.5, it made on ourdyno 219.9whp and 250bhp at 3ambefore that run.
Unfortunatley I have never had the following on the dyno though there are customers who are on the verge are getting these;
Fireballed Mary Head
MINI COOPER :: North American Motoring - FIREBALLED! RACING - The "PROJECT" formerly known as "MARY"
RMW Head
MINI COOPER :: North American Motoring - 231.9WHP with new big valve head. Stock cam and ECU.
Obviously Rolands stage2 head produced these results

I believe Rolands has a stage 4 cylinder head available now.
We can arrange the American heads for you without a problem.
