Engine Quest SBC heads?

Anybody on here use Engine Quest 350 SBC heads? I'm having an issue and need to compare notes, and there's very limited info on them on the internet. Thanks!

I had a set of their 180cc SBC cast iron heads but sold them along with a bunch of other parts to build a engine.
I believe they were made in Australia not China by the same company that cast RHS heads for Comp Cams.
Here's a website that has some flow number if that helps.
