Even with the tiny almost non existant quench pad, it is still a larger gain milling the head than the deck, as the bore is a concentric hole.
Still negating your argument.
Even though you said "water" I am assuming you mean "coolant". If coolant is 300 degrees, they must be running something special and /or using about 40 psi cooling system pressure.
You should eleaborate more on your statements, if in fact what you say is true. Nothing backs the truth like good ol physics.
Decking the block is NOT preffered for raising CR as much as milling heads, or using pop up pistons. Substantial Milling of the deck on some engines Like the SBC can weaken them considerably
Also when milling heads , if you mill to raise CR, then you most likely will be milling .030 or more, Milling the intake side of the head is a better way to fly. That allows you to run ANY intake you want . Milling an intake is a backwards way to approach the issue.
Lower CR in the early 70s was due to emissions and the cat wizz gas they started making. Low octane wont support High CR. Gas mileage suffered as a result.
