Well, I'm not sure what the header is but I'm going to coat it for preservation. Got an antique!!!!

Now, bad news on my block - it is 1mm over now as Mike says. So what are my options? I'm not finding greater than 0.040" pistons, 1mm over, and I've got to have this thing cleaned up. Do I have it sleeved? Or do I toss it to the curb and find another one?

If I have it sleeved, what do I go with, stock bore? I suppose that would make the most sense to get more use out of the sleeves. If that is the case then I can go ahead and order up the parts at standard bore.
