Best head for NKA clone motor


New member
What is the best head for an nka motor? Ive been told 181 but my research said there more of a plate head. Any information will help


There's a new 'best' head out about every 3months.
The latest 'best' I've heard was 223 or 233. I forgot.
Someone will post it.
Unless you have your tire and setup game down, chasing HP is not
gonna help that much.


So I have a 207. Who can confirm that it is not legal for nka? There are no officials for nka that can be contacted. I am putting one together for a November race and need to know for sure.
