Let's see here, 853 - 241 = ummm, looks like 612!

Seriously, I believe the 241s are later model heads, and they flow better than 853s, though I dunno how much better.

They same cast, just the 853 is sand cast, though , which makes the surface a little rougher, and if both heads are stock the 241s will flow better. If the heads are ported, then they perform the same.

The main difference is in the way it's cast. The 241 has the advantage till it's ported, then it doesn't matter. This has been covered numerous times, try searching first.
