All of the above make sense, and the most relevant tells me it is harderin 2021 to ride the combo ping-free bubble than it was in the early 90s.

See here's the thing; sold my 5Cs to a fella (oh he's happy), and only have the 48s andflattops. Flattops are part of a Crank balance.

So, i need 7M5, 4x, 5C, 6X or E or KRE, or Speedmaster to make a "Combo". Well, i hate to bare the 48s to dress up the low compression iron. Speedmaster?...! roundports?

Thinking to build the high-compression deal, break-in cam and rings, then remove the Top-end 48s For Sale as ported and fresh running set of heads, to recoup the low compression set.
