More power outta 460 with good alum heads or stroker with iron heads?

My first choice on 460 was polished and ported iron heads,was Okay for a couple of years then knew there was more.Went with Aluminum motorsport heads, Performer RPM, 850 dbl pmp, Tubular Automotive headers,Wow! what a difference.

P-51's 1150$ each, Lem sayes. And just a bit more into my acount and I will go for them Then I have to build the bottom he he, I know I start at the wrong end, but 545 and P-51's will be ok for the streets here in Norway
