72 360 first start question

with the piston as high as it will go (roughly at TDC) then back the crank up ~2" or so CCW then install the piston stop with the bolt down an inch or so then go back CW till the piston contacts the bolt (gently but firmly) & mark the dampener at the zero on the tab then go back CCW the other way all the way around till it contacts again & make another mark then remove the piston stop & turn the crank till a point halfway between the two marks is at zero on the tab & that is true TDC (piston at TDC and the slit hopefully right at the zero mark on the tab (which'd be halfway in between your two marks). are we on the same page?
