octane boost does nothing... it's been tested
however, 10.5:1 will work with proper quench, good cooling, premium gas, aluminum heads, a cam with a lobe sep angle of 110 degrees or so, bleeds off some cyl pressure. KB has a dynamic compression calc on their site - dont go over 8.2 or so and you can run pump gas just fine.
really it's all about the build. if it's done right, you can get more compression & power.
best of all circumstances: stroker kit that is checked thoroughly (eagle cranks need all journals checked for size AND taper especially at the edges because of factory methods)
perfect quench setup (.040) with zero deck pistons, aluminum heads, 10:1, 180 thermostat good radiator and pump
premium gas
if i was on a budget and had to choose between stroker kit vs. aluminum heads i'd go with the heads first. just put quench/zero deck pistons.
