Should all of these be replaced with new standard retainers or are there alternatives?

Valve Spring Retainer
Whilst rebuilding this Sprint head, I noticed four of the upper spring retainers had cracks in them. so I replaced them with some old ones I have. I removed two of the exhaust valves today (collars needed trimming down to allow shims to sit proud) when I noticed both of these retainers were now cracked. It could be that I missed these as they may have been hairline cracks. I've never had this before but I'm guessing it's from the extra lift of the cam, double valve springs etc.
Should all of these be replaced with new standard retainers or are there alternatives?

Replace and the split collets also. These do wear also.
