New pistons in 68 318

If you are going through all the trouble to "popping the pistons out:, you should go with new stuff. My 318 has over 100k on it and the pistons and cylinders look just fine. I pulled the heads and am having them done. I am leaving the short block alone for now. But I was ready go to the next step and pull the engine and do the pistons if they didn't look good.

If your heads are original 68 heads. And never redone, the soft guides etc for leaded gas probably need some help. And 60k your short block should be just getting broken in :)
