As posted earlier I am working on a 277 engine. I am dry fitting the sleeves. Sleeve stand out is to be between .0015 - .004. 1,3,and 4 sleeves are acceptable, but #2 is .003 on the distributer side and .006 on the manifold side. At first #2 sleeve didn't want to go in as well as the others, but after honing the o-ring hole in the block, #2 slides in just as easy as the others. Switching sleeves around does not correct this problem. I had the block dipped in town and asked if it needed planed, he said he would check it. When I picked it up I thought he said it was fine(have not been able to get back with him to verify this). Wondering what I need to do to correct this problem.
