i have a z3 head with two intake valves (bent) and i have a3 intake valves.the a3 valves fits in z3 head?

should be same thing. i have a complete set of a2 with 80k miles on them and z3 valves with 6k miles on them if you need some let me know

They do not use the same valves, but they may work. best to simply spend the 20$ or so for newZ3 valves(actually PRB valves)

 

[Jas9848]

from what i've seen all k-series valves are the same size/length, whatever except for the new tsx heads.

+1 Got a a8 valve in a z3 head at the moment due to a previously bent one, exact size and a perfect fit

check your valve guides. I bent a valve once and it cracked the guide.
