Stick to the ones that are well known. And yes they were cleveland ones.
Ditto, the castings were Sh!thouse!
I thought they looked more like an AFD copy? Especially when he mentioned the port size (wasn't a CHI port volume)
I'd be paranoid about porosity, or a valve seat falling out.... is a $1000(? not sure what the current prices are?) saving worth the risk of a dead motor?
I'd rather spend the extra money and see it go to the guys who deveolped the heads and cast them here in Oz, not something that's a shameless copy made in China... expect to see more of the great Aussie made Clevo stuff apearing as Chinese made copies... theres a Chinese TFC(?) manifold copy getting around now.
Keep the money in Australia!
