Performer RPM Cylinder Heads For S/B Chrysler

I hear you about the gears.
Many years ago, one of my friends was running a 427 in a 1966 chevelle and he had a wild camshaft + Victor intake + tricked out heads, so, he ended up running 456 gears..... The car was a total 1/4 mile machine, but, it was unbearable to drive more than about 50 km.
I'm not looking to race, rather, I am looking for minimal grief. Something that I can drive to California without constantly monitoring gauges + driving under 90 kmh or needing a jug of octane boost in the trunk for fear I may get a bad tank of fuel.
Hence, total daily driver type machine. That is what has me interested in some of the newer TBI systems. The ones from the 1990s were not great, but, in recent years, quality has improved and price has decreased.
As for the 273 block, I do like to keep things as "stock" as possible, but, it is not as though anyone can tell from a glance that it is really a 360.
