i have an 074 single head complete. no welds, dated 2.12.7 has had port work done to it. whats it worth? thanks for any help...don

anyone?

Sure the date isn't 2.12.70?

if it was 70, someone did a real good job eliminating the 0. i thought the same thing. but who knows. any value?

Being just a single and most likely a `70 date, I'd say it's worth around $750. The porting doesn't help it's value, probably hurts it, as some guys running in a class would need close to stock ports.
If it was a `69 date, then somone may need it to make their ZL1 clone, and might pay more.

anyone else have any thoughts?

Why not list it on Ebay? Set the reserve at what you think it's worth. If it sells then fine. If it doesn't, then you have a better idea of it's value. Just my view on things.
