Flat V8 heads.

[Torchie]

I have two heads for a flatty. One is stamped 59AB and the other stamped T9

I know what the 59AB is but what is the T9 from. My understanding is the T was a truck head but usually followed by 2 numbers. I checked a few other sources first but no luck. So here I am back at the fount.
Thanks as always.

I too believe theT is a truck head and an early 24 stud head. The 59 head is the best made for cooling and compression that is stock and used on a 24 stud block.
