Custom cam, springs, professionally ported cylinder head (piggy-backed someone else's race development), 3x2 45mm carbs
Stock forged diesel crank, stock L24 rods, stock KA24 pistons w/ valve reliefs machined.
Primary tuning (distributor advance curve and main/air jetting) by me, pro did further driveability tuning of carbs.
I chose to limit it at 7200 to have some headroom above the 6500rpm power peak. It held together over dozens of track events and 10s of thousands of street miles.
