What the stock rocker arm ratio on a BBC? Is it 1.7

Yes

My two cent's;
The stock stamped steel rockers are all over the place, the stamping process is fast and cheap, but not too accurate.

If you use the stamped ones I suggest grinding the stress risers off of the top side of the oiling hole.
I have sent the PR's straight through them before I started doing it. Now I have changed over to alm rollers. But you should be ok with a mild cam and springs.

I do plan on using Comp Pro magnums. They offer different ratio's and i did not know what the stock ratio is. Thanks for the info.
