4 hole valve covers for a 5.7 Hemi

Hello Everybody,
I have a 68 Valiant that is going to get a 5.7 Hemi (pre 08 block). I am going to run it using a carb with a Mopar timing case converter to run a distributor. So can you tell me if anyone out there makes 4 hole valve covers for the 5.7 Hemi? Thanks for your help.
