As said MAHLE will handle that power with ease, and what I use, just get machined for cut outs, if you want to use different cams now or later, std cams are perfect for that power level as is the std turbo.
I use B.E. Randal, of Hepworth near Diss, he charges a straight 1 hour labour fee for cutting the pockets in, which is either £40 or £45, some charge £9 per cut, x 16 cuts = £144, so bit of a saving, I've just rebuilt my engine and used std with pockets for any later cam change, going later on to use a turbonetics turbo, and want a BD14, which I will get brian(randal) to do by reprofiling a std cam, if enough base circle on them.
Their number is 01359 251888.
