They come with the head.. The retainers are chrome molley, but have a higher installed heaight, as in the head of the valve is down in them... I have no idea what brand the springs are.. but there SOFT as...
Im thinking i need new springs and retainers... as i reckon even stockies would valve bounce with a cam this size |

Not sure what mine are - I just asked for some springs to handle the cam. They are only listed as "Performance valve springs" on the receipt, and they have been shimmed up a bit. Not much help sorry.
I think crow ones are pretty good.
