Old non Hemi's were 5.5.
Hemi's are 5.5.
New Non-Hemis are 5.0mm.
I have the retainers for the stock 5.5mm valves.
I haven't seen the retainers for the 5.0mm valves, although I've been told they are much better than the stock ones for the 5.5mm. They are automotive style with split keepers.
If you have a 27mm intake on a non-hemi, it should have the 5.0mm stems. If you have a 25mm intake, it should have 5.5mm stems.
You might be SOL finding those 5.0 retainers and keepers.
Might have to install 5.5mm stemmed valves - which would need new or modified valve guides.
I found a guy on FB that might part with a take off set of 5.0 retainers and keepers if you need. I could probably initiate the parley.

Or I've been told that Dynocams probably has them.
Call dynocams and ask.
