What is the rocker arm ratio?

[Tbone]

I am having some head work done to my 2.2L turbo G head (stock 92 TBI cam). The builder asked me about the rocker arm ratio since the head is disassembled. I did a search on this site and found several answers:
1.762:1
1.75:1
1.74:1
1.72:1

Anyone know which one is correct?

Thanks.

Thanks. I told him the range I listed above and he said that was pretty close but he was going to measure it anyways. If he writes it down, I will post what he found.
