As Allports has said the part numbers would be better but the numbers you supplied mean
3D4 = 3rd April 74 so HQ or LH era
L is low compression
G79 = 7th july 69 HT era
3 A may actually be 3 H and H means High compression
E172 = 17th May 72 HQ or LJ era
If you still have any of the heads I would be interested in what part numbers went with what date codes.
Cheers Paul.
