That's not a squish gap but a deto gap. If you reduce it to half of what it is now, it will raise the compression even further but it will nevertheless reduce the deto risk.
He did, and so do I.
If he can cut a hemi shape, he can also cut an off-center hemi shape which is what you need, or you'll never approach the required volume.
I'm not so much worried about the studs, but what about the strength of the head itself? If you remove the required volume, will it still be strong enough for that methanol-compression?
use this:
HEAD.zip
It will allow you to combine any conceivable piston shape with any conceivable combustion chamber shape and display all relevant CNC coordinates, so any machinist worthy of that title will know how to produce your desired head shape.
I wrote this program a long time ago; it runs on Windows-versions from DOS 6 to Win98 and on some XP-machines, depending on their graphics card.
I myself run it on Win7 with a Win98-emulator, but I just found a simpler solution for you: if you restart Win7 in Safe Mode, it will also run, although not with all its original sparkling colours.
And in case you are using Windows 10: may God have mercy on you.
