So many different low cost combinations will produce at least that much horsepower when using those heads, there is just no way to give a single answer here.

It all depends upon how deep into the engine and what things you are willing to change, to make it all easily fit into whatever vehicle you desire.

This is from Scott Johnston (RHP - Parkland Automotive) face book page. I'm also posting a link to their FB page. They list several combinations to reach the 400+ HP level with a BBF in the 460 CI range. If you cannot afford a crate motor this may give you some ideas to work around.

Parkland Auto Machine added 47 new photos to the album: Ppam 468 Tow Pak. Regular Fuel combo. — with Billy G Hendrix.
September 29, 2017 ·
This 425ish HP combo is like our 450 / 460 HP crate combo but with 1 step less voodoo cam. 213 @ .050" VS. 219 @ .050" and 9.2 to 1 static c/r. 8.2 to 1 DCR at sea level.

I don't know for sure if each option is verifiable but here is a link to several HP possibilities with the BBF.

The simplest way for what you want is:
a flat top piston like Speed-Pro #H535P.
A good bowl port job on the heads with larger intake valves and a good high performance valve job
A CompCams hydraulic cam & lifter kit #34-244-4
Performer RPM intake manifold; the 8012 will work but, give-up lots of low end and mid range part throttle torque.
Just about any decent headers

Colt,

Though we have full porting instructions on our old RHP site for iron passenger car heads, that information is supposed to be accessible via username and password after a small 1 time fee. Where did you find these links?

Why are you posting direct links to information that is password protected? I will assume that this is just an unknowing mistake and that you will remove the links.

Thank you in advance.

I just googled d3 bowl cleanup and the information is on about 3-4 different sites.  Sorry I was unaware. You may have to edit your comment where you quoted me. It looks like the links are active in the quote.
