Okay what gives with this....hecho en china or hecho en korea?

If I was in market for bb heads, I would consider these http://www.starperformanceproducts....d-72cc-Chamber-BB-Mopar-361-440-Bare-3068.htm

I can't understand why people run from something because it cost less, we aren't talking pro wings vs nike here.....and besides, nike and the rest [minus new balance] are all made mostly outside of the USA...like most everything but the sticker the says made in the usa...iM sure it was
I saw those heads to...but they still don't beat the price of the china 440 Source heads that come complete and not bare...I saw a set of those ported on a 520 stroker that runs in the high nines....
