Are they atleast 6k output if so,thats fine.
1 - 6k isn't output, its resistance.
2 - Resistance does not equate directly to output. There are many things that can affect output other than resistance.
3 - More output is not "Better", its just different.
4 - More resistance is also not "better", its just different.
5 - If you're going to replace some awful stock pickups, don't replace them with a random budget line pickup just because its a manufacturer you recognise. EMG select pickups are EMG's cheapest line, are not made to the same standards as their Active Line, by a long way.
If you're serious about upgrading your guitar, then get serious about it. Don't try and shortchange it. There are some ripoffs out there, but your average "well regarded" pickup manufacturer, like Seymour Duncan or DiMarzio, charge a reasonable price and deliver a quality product. Most cheaper alternatives are just outright awful, especially for value.
