On OEM block its best to hone using the same gasket and Hardware to used in the end build, I have seen where using a stock replacement gasket 7733PT-2 and going to a 1003 Felpro gasket will change the bore dimension at the top of the cylinder.

OEM blocks are pretty frail compared to a Bowtie or Dart block

one other thing I have'nt saw anyone mention is that your torque plate needs to be close to same bore as block,Mike @ BHJ recommended within .060'',I learned this after I did my 305 the first time and used 350 plates when I tore down first time looked like had'nt had used torque plates.
Alot of people don't realize how much a stock block changes when heads are torqued in,most cases you hone with torque plates then remove them and go back and recheck cylinder bore w/ bore gauge cylinders are screwed up,reinstall plates and torque they go back like they were when you honed them.

One of the things that I have learned to look at with a torque plate is too make sure that the gasket fire ring is completely clamped by the torque plate. Many times I have run a gasket as close to the bore size as possible to gain compression. If the head clamps the gasket, then the torque plate must clamp the gasket. You will be surprised at how many do not look. Lay the gasket on the block, then flip over the torque plate and lay the gasket on it. You might be surprised, crap you might even shoooocked.
