To truly "blue print" an engine to actual specs and make make port heights and widths, deck heights, squish clearances/bands, CC volumes, crankshaft centerline indexing (TDC measurement accuracies) , rod lengths equal to precise measurements to go hand in hand with deck hts and squishes (already mentioned) and have all that actually MATCH what the mfr's truly base their "Prototypes" used in testing on,, would be a significant increase as well,, and IMHO add reliability as well
The fact of the matter is that they (Mfr's) cannot 100% control production tolerances to the penny (preciseness necessary) during production line assy, therefore the "production tolerances" allowed/settled for leaves a lot of room for perf improvement just based on a std blueprinting
I'm sure TC-1 can chime in on this as he has in past been a record holder in 1000' run competition

If it's cnote approved it will work good.
