which cam for stroker?

I built a 408 with stk Eddy heads and Hughes recommended their HER2228 (IIRC) hydraulic roller which will still run power brakes. It is 228/230 duration at 0.050 and about 0.550 lift w/1.6 rockers. They said I needed head work to run a bigger cam and then power brakes would be out of the question.
