I strongly suspect my local machine shop doesn’t keep a torque plate for a 235. Don’t sweat it???
The iron in that stovebolt block could probably be recast into 3 or 4 modern 4 cylinder engines. I doubt that you'll be able to notice any difference in cylinder roundness whether a 235 is honed with a torque plate or not. If you're really concerned about it, torque a junk cylinder head onto the block and hone the cylinders from the bottom side. I'd love to hide and watch that procedure!
