how do you figure out what octane gas is required for your mods and dome sizes???
For example i have a stroker crank, carbon fiber reeds and spacers, milled head(don't know how much), k&n, +4 timing. (All mods were done by previous owner)
He told me to run 110 octane minimum.
I have a cool head and 19cc domes new just laying around. Just wondering what octane i would have to use if i put the cool head on.
