The retainers looks completely different, they also look like they are steel and maybe even stock retainers. They don't fit well either. Did you get these heads straight from a vendor?
To the OP:
I looked up the cam specs. Per the way my Dart's were set up, you were very very close to coil bind. I would suggest you remove the other springs and get a valve spring micrometer and check the installed height.

I'll do that for sure, what is the procedure to measuring installed height?
