check out LAST months 5.0 Mustang. They flowed better than GT-40x heads...and similar to TFS only they are Iron...which can make them more daily driver friendly. I will be ordering a set for my 351 long rod combo...they are supposed to work wonders on this idea. It all depends on you combo my friend!
basicly a better cast and slightly revised set of windsor sr heads.
you can get large flow numbers from sr heads and i expect the same from the roush. i was gonna get them but i stuck with my aluminiums for weight
