I removed the heads from another engine and had them reworked at the machine shop. I was installing them today and ran into something I had not experienced before. On the drivers side head the top holes in the head do not exactly line up with the threaded holes in the block. The bolts drag against the front of the holes in the head. I tried it back on the old engine and the same thing. It must be bored wrong. The bolts will go in but the drag will make torqueing it incorrect. I am using ARP bolts which have a smaller shaft diameter except for the top 5/16 so they only scrape there. At this point I could shave a few thousands off of the top part of the bolts but I really don't want to do that. I guess I could open up the front top of the holes in the head. Has anyone ever ran into this?
