882's are not a performance head. flows pretty good but doesn't make the power that a set of D-humps will make. Wouldn't be bad for a back-up motor.

hughes is right,here is some additional info. 882's were made from 1970 to 1980.They were some of the first "smog" heads.The chambers were enlarged to lower compression.They flow much better than later model type smog heads.So,if you can't use double humps (or better) these are probably your best choice,best of the worst,so to speak.

My brother has a set of 305 high output heads? I believe they are. what is so good about them? What should I do to them to make them perform better?

I'm not familliar with 305 heads.In general,simple pocket porting will help quite a bit.There is book written by David Vizard, I can't remember the exact title,something to the effect of Performance Modifications to Chevrolet Heads.(I have it but it seems to be misplaced at the moment)This is an excellent book,easy to read and techinical at the same time.David Vizard is THE head guy,he has an article in the newest CIRCLE TRACK.If you want to know something about heads or do some porting,this book is a must have.I bought mine at the mall book store

The 305 HO heads are 58-60 cc combustion chamber heads. The intake tract is small, and they are the lightweight( easy to crack) heads. I have a couple sets (NO, they are not for sale) of the 450's and the 601's. I ran them the last 2 years and did not crack them, they got pretty hot too. If you are restricted to flattops and cannot run early model or vortecs then they work good to bring your compression up.

we were req by the rules to use the 882 heads specificaly on chev engines with no port work and retaining a min 72cc chamber .
At the time i had access to a flow bench and found 882s from the 400 ci eng to flow best
but if you can use some thing else DO IT these heads are prone to cracking hope this helps
