You asked a similar question a while back, and I provided an answer -- at this stage I think the answer is the same, with one difference (bolded below)

At present:
In future:
- Confirmed: J-10Bs produced, powered by Al-31s with one large batch complete
- Confirmed: more J-10Bs powered by Al-31s (batch two)
- Confirmed: J-10Cs powered by Al-31s undergoing flight tests, likely preparing for production soon
- Confirmed: one J-10 prototype airframe (likely J-10B, possibly 1035 from a few years back) seen doing flight tests with a WS-10
- J-10B (powered by Al-31) production will be superseded by J-10C in mass production, where an initial batch or more may be powered by Al-31
- J-10Cs in production will eventually be mass produced with WS-10s
Arent Block 02 aircraft J-10Cs?
The latest images (November 2015) indicated that the production of 02 batch continues. These are thought to be the improved s with VLOC antennas installed on top of the vertical tailfin and carrying the new PL-15 AAMs.
A picture posted by ShahryarHedayat on the Persian Gulf & Middle East Military News thread is kind of interesting. Look at that humongous J-10 painting behind the two generals in the background. It's that the Chinese subliminal message of "Buy J-10! Buy J-10!" to the Iranian delegation? View attachment 21192
The J-10A cannot be exported due to engines.
