i was wondering if the valve covers are interchangeable?
k20a(2,3)
k20z(1,3)
i dont think the k24's can change to the k20's but are the others interchangeable?
i ask because i little bit back i posted about painting my valve cover and as i was looking at the valve cover on the k20z3 has two more holes than the k20a3? is it still interchangeable or is there no way the valve cover can be swapped on to the k20z3? any help would be great.

 

they are interchangeable.

 

thats what i needed to know. thanks for the help. is it still ok that the k20a3 does not have the extra two holes?

 

i sprayed the valve cover the other day and it came out better than i thought it would not great but pretty good. got some pics i will try to post them up if anyone wants to see them. not the best work but i think they look good.
but i would really like an answer to the question about the extra holes in the k20z3.
trying to put a k20a3 head onto a k20z3 i dont know if i put that in my first sorry if i did not.
