Default Spark plug threads

I need to find out what size the threads are on the LT1 spark plugs . The PO cross threaded 1 of the plugs and I want to run a tap through the head from the rear and hopefully straighten the rest of the threads out before I put the head back on.

Take the spark plug to NAPA and have them sell you one that is the same size/thread. This way you
dont have to sit at home waiting for someone to respond or to post a "lurk" smiley.

Yeah I did that and the 16yr old kid that should be working at sallys beauty supply didnt have a tap and couldnt tell me what size thread it was so I could go buy it somewhere else. I thought that maybe someone could help me out on here and I could just go buy the tap and chase the threads.
