Did they deck the block ? If not that could be the reason.

Normal for the the Oldsmobile 307 and 403 blocks.
They are of a lightweight design, light and have scalloped and windowed mains. For a full race engine, you can fill the block and used a girdle, or sleeve to a 307 bore size, a 1968 thru 1971 high nickel block.

Yes block was filled to bottom of water pump holes. Didn't know we could run a stud girdle. Ill look into that. Block was decked. We actually had to cut .034 to get zero deck. I have a 71 350 block but being a budget build I didn't want the expense of sleeving down to 307 bore

Slow progress but progress. Cleaned up oil passage on main cap. Removed burr on hole entrance and the port to block had a large restriction dog leg in it. So I straightened dog leg in port. The oil hole in block was about .060 smaller then oil hole in cap so I matched those. Drilled and tapped passeges in main caps to run oil restrictors.

Kinda thought that is the reason for honing with a torque plate, to make sure the cylinder is round when the head is bolted on.

LOL. My significant other doesn't even know about the first dollar spent on this project. I type this stuff when I'm by myself. Thanks for catching it. Now updated. Also I need to get my pics on Flickr or if someone has a better place to host pictures.
