As the Avanti head is recessed, & the 2mm squish band sits inside the bore, does this mean my desired btdc timing of 17° (which equates to 1.6 mm) should read 3.6mm on the dial gauge, or am I spectacularly wide of the mark?
Also I noticed on another thread, that when setting the squish, solder was played across both the piston crown & measured, then some across the cylinder head squish band & measured again. Is that just a belts & braces affair, or could there be a difference?
