everything in the top section. EDIT piston vol is the cc's of the valve reliefs or the dome cc's whichever you have. they changed the format some as they used to prompt you to enter the cc's as a negative # if it is a dome but iirc you have flat tops or valve reliefs so you're good, just lookup the spec for your pistons and enter that figure w no neg or positive notation and let it do the work from there
