retorque heads to solve issue?

I had never had to retorque head gaskets either until I had some seepage from my latest set of cometics. It was barely noticeable (drove around for three years until I noticed it) I only noticed it from the dust collecting on the light haze of oil and it looked just like the ops. Called cometic and they told me that happens sometimes and it can be the finish of head or block (mine were finished correctly), aluminum heads on cast iron block moving around, or just because lol.

I also mentioned the overhang of an aluminum head on a small block mopar and it putting pressure down on the rivet and "flexing" the gasket down slightly and they said it wouldn't hurt to drill out the rivet. They recommended the retorque and said it may work right away, take a while to work or always seep lol. They also said it will not affect the engine so I figure it may be something I just live with and wipe my block down once a year instead of never in three years.

I remember way back in auto shop it was a common practice to check/retorque head bolts after break in, seemed like an industry standard at the time. That supposedly went away with better head gaskets but as we all know in this hobby it aint always the case.
