Spoke tension for V170 wheels 27 x 1 1/4

I am trying to find out what the Apple tension should be for a 36 spoke steel wheel (V170 made in Canada 27x1 1/4). Spokes are 2.0mm steel. Tensions are sitting at 17 (park tool gauge) or 53 Kgf.  Wondering what they should be?  Would love to know front and back. Wheels are from a 1977 Targa 10 speed.
