I guess I need to buy rocker arm assemblies for my 292 rebuild.  I see Mummert sells them for $950.  His are 1.74 ratio.  I have no problem with good used parts.

My Question:  Are the used ones pretty much all the same?  Are there different rocker ratios out there?

I found a set on ebay off a 239.  Will these fit?

You guys are the best.  I know I am going to get all kinds of info on rocker arms.
