1550 valve?

I bought a 05 Road King with screaming eagle heads and the 1550 big bore kit in it. I'm in need of valve guides. Is this the correct kit for the big bore kit?

Are these valve springs included or compatible with 30003-10 883 to 1200 conversion kit stage I? Will it improve preformance in any way with this kit?
