I am not sure what you have there. The Pond stuff was not made until about 2007 or so. May be some old Dove stuff that you have. I would just replace both heads. We use Edelbrock and Pond and they both work fine. We have them in CNC ported versions that work well and they run about 2600.00 to 3000.00. Feel free to call us at 870-246-7460.

Thanks, Keith
