The easiest and simplest way to tell an S14 SR20DET(Zenki) from an S14a SR20DET(Kouki). Is that on the Zenki engines(93-96) the valve covers had Stud and Nut combination for the attachment, while in the Kouki(S14a) engines it used a Bolt and tapped hole in the head similar to the KA. This is one of the Minor Changes(MCS14).
