I posted this last week trying to find some info on this mystery casting number but have come up with zilch, like they dont exist. They have CFD cast in them as well as HI PERF. The date code is only 58. They are rect port iron BBC heads with 2.25 valves and bronze guides. The main reason I need some info on them is I would like to sell them but I dont know which class can use them. They are fresh with new valves and guides and triple springs. Any info would be appreciated.
