cast #2780559 = part #2780557 ('66-'71 "street" HEMI cylinder head)
are you sure those "3"s are not "8"s? (or were they still casting "street" HEMI heads in '73?)
month*day*year
G*28*8 = 7/28/68
E*29*8 = 5/29/68
H*14*7 = 8/14/67

They did cast heads and blocks in 73 but I'd agree with your first date breakdown on these examples.
