So I'm curious about how to go about picking rocker arms. I understand the ratios and what it does to valve lift, but I'm more looking at what is and is not interchangeable. Ford didn't really create 1-off rockers for the small inline 6 did they? Would they do something that foolish? Can I use the adjustable rockers from an FE without a significant amount of pain?
I would like to find an economical set of adjustable rocker arms. I know CI sells the adjustables for about $300 (assuming some shipping cost there). But, I can find FE rockers on the ebays for significantly less...
What I am up to for some background information: I'm intending to keep the stock cam for now as this is a head swap/upgrade. I'm not necessarily looking to change the geometry, but looking for adjustable ones because I'm planning on having the head milled to compensate for the larger combustion chambers (Large log replacing a small log). An adjustable set, in theory, would make that transition easier, right? I'm planning on measuring each chamber and my goal is to shoot for something in the neighborhood of 49 cc. Which would mean milling in the 60-80 thou range if I math'd it right (assuming the head is at the spec'd value of ~62cc).
Does this make sense or will my non-adjustable rockers be just fine and dandy if I acquire shorter rods?
