One , or actually 3 principal words:
Let it breath.
Inlet, exhaust, different cams. Those are the things to start with, do it in stages. Imho, THE place to start with is the exhaust manifolds.
Look closely at racing engines, then look at your engine, notice the differences in the breathing area, and adapt your engine to those, you think might work for you. It's no rocket science.
Tubing from and to each cylinder should be equal.
"Flowing" the stuff is best, it is possible to build a home build flowbench if you fancy the work of tuning yourself.
Not top notch, but it got me there when I still raced in the late 70's,
With home built stuff we achieved 145HP out of a standard 85HP 1.3liters Simca engine.
Machining some of the stuff is left best with proffessionals, like valveseats and stuff like that.
If you've passed there, then try to find somebody you trust to fumble with the computer.
Be aware though, I've mentioned it before, the limit of the gearbox is 320Nm. You won't be the first one to break the diff. casing.
