441s are less crack prone than 882s. I always thought that 441s flowed better too.

Also 441s have 68cc chambers
the 882s have 76cc chambers

441s are somewhere between 74 and 76cc. They also take the washered spark plugs where as the 882s take the tapered seat type.

For a mild street application look at the flow numbers from .300-.500 lift. If you use a cam with .450 lift and you select a head that flows the best above .500 lift your combo will be weak. 441's have a 73 cc chamber according to Car Craft. I've heard the stories about cracking 882's but I've never seen it happen, wondering if the heads were heavily ported before cracking, IDK. I'd say go with the 882's if you're on a budget and if you want a high revving motor/big camshaft junk them both and go with aftermarket heads.

441s are make a better head as long as you put hardend seats in them.They also have better ports and alot better casted runners than 882s.882s have that hollow spot in the runner underneath the rocker arm stud that doesn't help flow any at all.

about 75% of the 882s that i've ever seen end up being cracked.I remember reading in a book where this guy thought GM actually cast the cracks in at the factory..lol 327,350 and 400 heads are all bad to crack though. I've never seen a cracked 305 head and i've been around ALOT of those.

My dad and i have a few sets of heads in our collection...this is part of them.

The stock 882 heads outflowed the stock 441's, especially at .300 and .400 lift. Apparently the sloppy intake ports of the 882's didn't hurt the airflow.
