Piston question

Dart
.060 squish/ quench is a problem
look where the spark plug is
look at the small gap to get to the intake side of the chamber
how is the flame front supposed to navigate that gap
you go big like with unmilled heads and the piston down the hole still not good but better as the combustion can start all by itself at the back side
with tight quench- tight cold surfaces .030-.040 between them the flame front cannot travel so no light off - much less chance of detonation
plus the squish where you get turbulance to really light the fire
your build will be much more "crisp", responsive
try and get .040 or less or over 100 (the factory sogger way)
cheers
and no the compression you mentioned is not going to work on a street motor
unless maybe you get YR to tune it for you or e-85- or water injection, electronic ping detector, etc
learned a lot in the last 50 years- keep your eyes open
