You better have an LT4 intake to match. Don't expect to use them with a stock LT1 manifold because it won't work.
But let's say you have an LT4 manifold to begin with...by themselves they will provide significant gains over stock. The real power can be had if they are ported even further. Will they make more power by themselves untouched over AI 200ccs given the same camshaft? Debatable. Can they make more power than the AI 200cc package when ported? Absolutely. Tons more.
AFR heads are very stout performers in the hands of a competent porter. But like I said, you need an LT4 manifold for them to work.

100% CNC doesn't mean anything.
As cast, they flow nice don't get me wrong, but there is plenty more material to be taken out.
And IMO, if you're spending that kind of money on those heads, you're serious about your build and you'll want every CFM out of them that you can get.
