Do we need to wipe cache and dalvik cache before flashing a kernel?

Yeah. It's always recommended you do that.
although some kernels do this cleaning during flashing but I still recommended you do it for every kernel to minimise possibility of any problem

dumb question but uh?

hey guys i wanted to know if i had to wipe everything when there is an update for a rom? or just wipe cache and dalvik?
thanks
It's a case-by-case thing. Sometimes you only need to wipe caches, but others you'll need to do a full wipe. Usually a ROM developer will note what you have to wipe when they post the update, so make sure to check.
You could always just do a nandroid and then try flashing after a cache wipe. If that doesn't work, you can either restore or do a full wipe and reflash the update.

I always factory reset. Wipe cache, then dalvik. Twice in that order. But you can get away with just wiping cache and dalvik. As most will tell you

Note that the MeanROM installation will wipe cache and dalvik cache for you, so no manual wiping is necessary actually.

No you dont have to wipe data/factory reset. you should wipe cache and dalvik cache though.
And what do you mean what should you do next?
You could use first a kernel cleaning script, take a look in http://forum.xda-developers.com/showthread.php?t=1363738.
I have just flash the kernel after cleaning cache and Dalvik.
Thanks to you all that what i want to know

Bootloop after installing Lollipop

This happens every time I flash any lollipop ROM, it seems to work with Kitkat ROMs though. What should I do? And yes, I wiped dalvik.
Before installing any rom at first flash stock rom.
Go to cwm or any recovery Wipe data, cache, dalvik cache. flash rom & reboot system.

Yes, I know. This isn't the first time I flash a ROM, but this is the first time I get a bootloop even after I wipe dalvik cache.

Question about TWRP...

If I wipe Dalvik / ART Cache, System, Data, Cache in advanced wipe option in TWRP before flashing new ROM for clean flash, Will it remove TWRP too from my phone?

You sure? What partition does TWRP or other recoveries get installed in?
To the recovery partition, the one you usually dont ever wipe unless you flash a new one.
