As long as they are within tolerance, rated at enough power, and have low inductance (including the leads).
Try to find a service manual. eg.Google "Make model Service Manual". Perhaps a parts list will specify. Lacking that, I agree the "K" may indicate 10% tolerance; conservative assumption would be that each series resistor is rated at 5 Watts. Select accordingly.
The two end leads look suspicious. Try a bit of flux and resolder them. Maybe you'll be pleasantly suprised.
Good luck!

You can get a service manual for one but not the other. The left one is open one side the output transistors were shorted. They are both different units from the same manufacturer. Really appreciate your help guys. Thanks.
Interesting
Doing few searches seems to be Non inductive metal foil , flameproof
common cross reference leads to Noble RGC55 series
seems common with appliance repairs also, likely because flame proof
doesnt look like Noble but dual package.

So what is the reason for replacement? I see a lot of unnecessary replacement of components in threads on this board. If it ain't broke, no need to replace. A lot stems from inexperience, replace and hope technique.
It may look silly, but provided there is sufficient space - two resistors BPR58/KOA Speer/:

Better still BPR55 but.....

Thanks for that I am sure they would work fine as well. I have discovered that four other resistors are open as well R5441,R5442,R5450 and R5460. I have also discovered that this board is identical to the one from the AVR400 model and there is a schematic available for that, Which I have attached. The problem is even thou they give the value there is no indication of the wattage. I have heard you can get an indication of wattage just by measuring the size of them, is that true and how accurate is that? Thanks.
Most of the resistors appear to be surface mount. Study this link for guidance; ask for help if needed.

If your attached service manual is accurate, that's a big help. Many, but not all wattages are noted in the schematics, but I'll admit to having a hard time spotting the Ref Des in the schematics. I did spot R5450 at drawing grid D4, PDF page 31. You'll probably have an easier time with the unit in front of you for guidance.
Maybe this will help get you started.
Good luck.
