I got told to throw in the bin but then i measured the ports and they're rather large! Anyone know what they're worth? I know they are 308 but wouldn't know where to start asking about them, thought i would give on here ago. A Holden guy said they were genuine L34 heads? Some original photos have not been recovered yet.
