There is often controversy over the legibility of the numbers in the castings — while it appears that the 6’s look like 8’s the reality is that GM has never produced any “482824” castings.
According to John Lingenfelter, in his book these heads made his short list of iron heads to use for performance builds.
One of the great finds for this project were some older GM Performance Parts (GMPP) iron heads. These complete “624’s” were advertised locally on Craigslist and for $250 the Seller threw in a 7 quart Moroso Oil Pan. They looked in good shape but as always, you never know what you’re really getting until you can take a closer look, but I took a chance and made the deal.

Well, there's good news and a little bad news about these heads!
The Bad News; these heads are crack prone!
:roll:
So, before sink a bunch of $ [links]
The Good News; Chevy used these heads from 1976 to 1987 on 350 cid engines.
They were fitted with either 1.94" Intake/1.50" Exhaust, or 2.02" Intake/1.60" Exhaust Valves, all these heads had 76cc combustion chambers.
Are they good or bad? Depends on the heads actual condition and your plans for them.
Could be either way.
As for as making power, yep!
They'll do that, depending on condition.
Good valve size, nice combustion chamber size depending on the pistons used with them.
If there are no cracks, build'em and run'em.
If they have cracks, swap'em out for a better set of heads. [links]
