500 EFI Question

Does anybody know if 2000 hp 500efi's come stock with gold roller rockers ? I"m trying to determine if any valve work has been done on these engines.

The engines have 300 easy hours on them and they run great. I had heard that the valve springs were alot better in the EFI's than the carbed motors is that true ?

They did get a little better but still have the same issues as the carb motors. If you pull the valve covers and take a look at the inner springs you can usually tell along with metal pieces like glitter laying along the inside lip of the head at the valve cover. If you have this you may also want to pull the heads off and replace the head gaskets as well.
