Re: ebay aluminume heads???
There is people testing these chinese copies at the moment on the other forum "au" forum i listed in the other thread.
It has detailed pictures and independant flow figures.
They have some nasty steps under the valves which hinder flow a fair bit.
In the low lift, they are worse than std 2v heads, but with some work can work well.
But then may as well buy AFD etc.
