Hello..
I have a new to me 582 bbc it was in the dragster when i bought it..i decided to have my motor guy take it apart,,being when i went to put lifters in, the cam had a chunk missing from a cam lobe.. :x .
H e mensioned to me the motor is useing copper head gaskets and the block is o-ring'd.
Im not an engine builder he didnt say if this is good or bad.. so is this a bad thing?

Thanks In Advance
Keith
