What are the best heads for a BBC? BBC, 454.. if you need more information let me know!
What would be the best heads? A link would be great. Looking to make ~500hp with a solid H/C setup, but going to wait on the cam for a little while.

Unless you want to save weight, a set of regular oval port heads with a bit of bowl blending and a good valve job would do the trick without any issues. Probably be 550 HP with the right cam and intake.

For your BBC stick to oval port heads under 300cc runners. On the cheap you can get a set of stock 781 oval ports and have them worked or for some more money you can get some Brodix oval ports. Also you don't need to go solid to make the numbers you want, stick to hydraulic. Check out engine masters, there are LOTS of BBC builds in there.
I would go hydraulic roller. But the heads we speak of are used, you will need to search for them, call a machine shop, check racingunk.com, things of that nature. Avoid the peanut port heads, they look like ovals but are way smaller.
World products merlin heads are the cheapest USA made head.
And get Howards direct lube lifters, screw roller stuff, unless you tell how much money you're looking to spend.
600 hp big block-
large oval port heads
11:1 SCR, 8:1 to 8.5:1 DCR on pump gas
a cam that will get you 8.1 DCR with 11:1 SCR
1 7/8 headers to 3" exhaust
850 cfm carb
Modifed stock HEI
170+ lph fuel delivery
How long it makes 600 hp depends on your selection of bottom end parts.
Like i said, unledd you want to save weight, the GM factory oval ports would get the job done, if you wouldnt mind spending money, the aftermarket can lighten up the engine with aluminum heads that are ready out of the box.

About how much are the aftermarket? the GM factory?
Aftermarket, Pro toplines go for 1200$ asslembled, Dart 1500$, World 1500$, that is all cast iron. Aluminum: Patriot 1500$, Brodix 2200$, Camfield 2200$, AFR 2200$, Dart 2200$.
Take you pick for the aftermarket, those are going prices. I have seen GM factory castings for 200$ to 800 $ on Ebay, craigs list and all those places.
