well said Ben..
Although parts and tuning has come a long way, when you improve in one area you will have to improve in the other..
Also keep in mind when building 2MM engines to always use authentic OEM Mazda FD 93-94 Apex seal springs, side seal springs and corner seal springs. They are able to withstand higher temps for longer periods of time.
All others that i have seen will loose deflection with one or two passes down the 1/4
