I think John could use a nice high effort iron head porting job to help fill up some of his leisure time.
Plus it would be nostalgic........ Bringing back memories of 30 years ago when porting iron was the only option.

I've had a couple sets of iron MW heads in my shop that were ported by a pretty high profile non-Mopar engine builder. These were fairly high effort(high dollar??) jobs, that looked very nice.
One set was some OE 286 heads, the other was the latest version of the 518M heads.

I'll just say that neither set had the kind of flow numbers I've heard that these heads are capable of........ Although they flowed basically the same as what I've gotten out of them with my "normal" port job.

Admittedly....... I'm not into fixing holes...... So I err on the conservative side...... Which means there is some flow left on the table.
