This initial post will be pretty short, with other/more info to come along at a later date.

Someone bought these bare and sent them to me to have them looked over, corrected as necessary, and assembled with known quality parts.

I see a 265cc unported version and 325cc CNC ported version listed on ebag...... So I assume these are supposed to be the 325cc version.
I haven't cc'd one yet, but they don't look like they're going to be as big as 325cc's.
Especially if the unported ones are anywhere near 265cc, since there are several drop outs(areas the porting program didnt touch) in the port.
They are still std port opening on the intake side, and the exhaust opening appears pretty generous, measuring 1.790 x 1.395.
The current prices I see over on the bag for these heads are about $800pr bare/unported, $1500pr bare/CNC ported.

As with most Chinese heads I see, the valve job is "small", 2.10 O.D. for the intake valve, 1.72 O.D. for the exhaust, and both will benefit from the seats being recut and then having the new seat blended into the bowls.

However.......it's very likely someone will end up running some of them OOTB, so that's the place to start.
I have no idea if the assembled heads get any additional seat work compared to the bare heads, but if they don't...... This is essentially what you'd have.
I used some Indy 2.19/1.81 valves with no back cut for this first test.
