Damaged/Abused L92 Cylinder Head for use as a porting master

[ChevelleNV]

I am looking for one damaged/abused L92 cylinder head to use for a porting master, need only have one or 2 good cylinders so I can port it, drill holes to check wall thickness/etc. it will only be used on the flow bench so it don't need to be pretty. Let me know what you got...
