the 882 is light, the 624 is really light, both are prone to cracking, both make good boat anchors.

 

I hear they're real good for porting practice.

 

If you dont get the 882's hot they are very good street heads. Getting them hot is the only reason they should crack. We have had a set on our bracket car for years with no negative issues

 

882 have a slightlty better designed exhaust and slightly more durability with heat issues but they
are very similar.
