I would only buy them when its from a legit company who buys the casting and inspects them before they go for sale. (Like Goatzilla probably does) Even better if its someone who buys the bare castings and puts quality components in them.

For sure its a much better deal than going through factory iron heads. You will for sure bolt on power.

WIth that said, Im building a budget BBC for a race car. EVERY SINGLE dyno I have seen that compares speedmaster/Promaxx etc chinese castings to a serious set of Dart or Brodix heads, they give up significant power to the American castings.

So for budget better than factory heads, yeah no brainer. But as cast you are going to give up power to most bigger name heads.

He already did, he cut a head apart to check the core and deck thickness etc.

Yeah I followed that some. But does every one come out of the box? I would guess he does but I dont actually know.

The knock on the foreign stuff, be it a head or a distributor cap has always been QC. For every few people who have a product that worked great there is a guy who had one that was all the way bad.

As I earlier said, I think the best bang for the buck is buying the cheap bare casting, having it inspected and having quality components used in it. I know people like Skip White do that in the BBC world, I dont know about the pontiac castings.
