I posted this over in the classic section, as these are gen 1 heads, that will evenutally find their way atop a lt1 after being converted, should the heads be worth anything.

original thread

basically, one the chambers got fragged with an exploded piston, the previous owner decided to debur them, and in the process removed quite a bit of material around the spark plug opening in the chamber.

the other head has a discolored intake runner, and i am not sure what would cause that....

thanks for the help. if this thread is deemed inappropriate or inappropriately placed, i apologize to the moderators.
