Finding the wrong groove.

As I am still waiting for the new piston rings I thought I would crack on with the head.

Simple job of putting in the valves, seals and springs before bolting on the rocker rail. First of all I stripped and cleaned the rail and made sure all the oil ways were clean. I then reassembled with assembly lube.

I lined up all the valves and slipped on the new valve stem seals. I compressed the first spring and placed the collets on the valve stems. Upon releasing the compressor I found a snag. I had bought single groove valves and collets, but the spring caps were for the later (and correct for 05 KD 28) three groove valves and collets.

I am now have a quandary. Do I double down on the mistake and get new spring caps or go for the correct valves? I am thinking the later although it does depend on the valve clearances in the guides.
