Which rockers to use??!!

I've got a 408 stroker, Eddy heads, Comp Cams XE274H cam. I was planning to use the 273 rockers but a few have told me not to use those. So I looked at the Mancini Proforms...same thing..don't use them!! Any rockers that are less that $500 that will work on a fairly mild 408!!?? This is nuts!
