What do I get for the next bike?

2.1-2.14 mm squish. Lots. I'm told I can go down to 1.3 mm safely on pump gas.

That's with a 0.5 mm base gasket
I'm basically flush with the exhaust and transfer ports at BDC.

Do I swap to a 0.2 mm base gasket (which only nets me 1.8mm squish),(0.3mm gain) or get an
Aftermarket / milled head?

I ran it. It worked amazing and the bike has better power than ever. It's super snappy and feels great with the jetting change.

I'd still like to experiment with a better shaped head for improved gas mileage and hopefully some power- then I could gear up and have some longer gear ratios and pull a higher top speed or just motor in a higher gear up hills.

I was a little nervous because I changed to a fatter idle jet (up from 25 to 30 maybe?), blue needle (richer) and found the lower rad crossover hose was cracked so I had to replace it. A new chain and totally rebuilt my forks from ruining them at Rhino with new SFK seals, dust seals and mud scrapers. Expensive compared to regular stuff, but they are the best.
