I used the Race Logic templates to port my ZR580 a couple years ago. I am very happy with the results. Not only did I get to buy some new tools, a die grinder and long reach carbide burrs, but I got a performance bump and maybe even a little bit better on fuel. These templates, and this porting has nothing to do with matching flanges. On the 580 you could look to a bump of maybe as much as 10 HP, but probably less.

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
