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 http://www.mini2.com/forum/engine-dr...ow-graphs.html

I believe Rolands has a stage 4 cylinder head available now.

We can arrange the American heads for you without a problem.

Will fitting any of the above heads have any significant affect on reliability? Or has not enough testing been done?

How much does the fireballed stage 2 head cost and is it on exchange basis?
