I used a reputable engine place about 5 years ago. Like this one they do any and all engines - Hyundai to Toyota, SBC, MOPAR, etc. Replaced the engine a few years later - too many short cuts.
Below is a quote from Hi Performance's home page:
We value our contacts. We firmly believe in collaborative, expansive networking and global sourcing for quality custom, OEM reliable, affordable products and services that meet and exceed consumer expectations.
Emphasis mine to high light that they are telling you they will use Chinese parts when they can. Having 30+ years experience in procurement and most recently with a global high tech firm and doing a LOT of global sourcing, this is a danger signal to me. Would love to sell them a core block for $300, tho.

You gotta have the right tools and know how to use 'em.
