I need to replace the valvetrain in my K24 head, can I use K20 parts or does it have to be K24 parts?!

It depends on which K24, the K24A2 yes, all others no.

The springs, retainers and seats and valves will work, but the rockers and cams are of a different design.

If you use dual valve springs from a k20a2 head you will have to change the spring seats in the k24 head. Wich require that you take out the valve guide seals.

The rocker arms you can use the k20a2 but you have to lock them in vtec and use vtec cams in your k24 head.
