rocker arm ratios

I saw a article in Hot Rod several years back that said a higher lift rocker arm set was used on certain years of the slant 6 and I am interested in using them I think the standard is 5 to 1 and the ones in question were 6 to 1. Would it be worth the cost versus horsepower gained to use them I have oversize valves!

No, the OEM rocker arms are supposed to be 1.5:1, but they are in reality, more like 1.35:1, so higher-lift rocker arms are worthwhile... if you can find any.

AFAIK, no "high-lift" rockers ever came on a /6 from the factory.

Good luck.
