i have a sb 350 with the casting number 882 on them i know these heads are ok but what ones are better to put on? im only rebuilding my motor and going to try to push like 400-500 hp

 

dart is a good head.

 

For what it's worth, I previously ran numbers on my own engine in Desktop Dyno to do a head-to-head comparison. Among a number of the well known aftermarket aluminum heads, the AFR ones yielded the best power boost. And the 190 cc runners showed better flow than the 210's. Bigger isn't always better. I don't know if aluminum heads are in your budget? But better flow capabilities, the ability to run a higher c.r., and lighter weight, is worth it in my book. They're on my want list.

 

Camaro 69: Know anything about the Patriot Performance aluminum heads? They seem like a great product and are only $895 assembled for a pair...

 

I don't know a lot about those. If I'm remembering correctly from what I've read, aren't they fairly new in the aluminum head market, maybe a couple of years or so? I need to see if I can find some DD flow files on those so I can plug em in.

 

If you can find them, a set of factory 194 or 202 fueler heads are pretty hard to beat for a street car.
