whoa buddy. you get what you pay for. ive seen those heads run great after $1000 in machine work/porting(ran on a 700hp chevy 350). but thats the only way they will even run....they make great door stops too!!

I have heard that the quality of the machine work on these heads can be pretty poor. The rocker arm studs were out of position and some studs weren't sitting perpendicular to the head surface. In other words, they were leaning to one side. You may luck out and get a good set or maybe you'll get a set with the above problems. The castings can also have their own set of problems with pin holes in the water jackets or else where.

I read about these problems on one of the forums, so take that for what it's worth. It's a gamble when looking at heads with their price being half of what a good set will cost. These heads come from China by the way.
