They shouldn't need anything special. The only thing would be if you want auto lateral tilt. Then the headers would need sensors and a wiring harness to talk to the combine.

 

Nope its all the same. A few years ago we bought the tilt kit and put on an r76, connections and mounting to header are all the same.

 

I believe this is partially correct. The combine lat tilt kit "is" slightly different for the late R62/Rx5 series vs Rx6 series. Gleaner went to a different hydraulic manifold system in the Rx6 series so the lat tilt valve is a different part. There might be other small differences but the slightly different hydraulic plumbing and tilt valve were the biggest change.

Also the early 62's had a different lat tilt feederhouse. I believe it was 98 or so that Gleaner changed to the current "standard" lat tilt feederhouse, about the same time as the 800 series flex head came out. AHHC system also changed about the same time from the 3-spring sensor system to the infinite potentiometer type sensor system. Pre 800 heads would not fit the current standard lat tilt feederhouse. If your combine does not have the lat tilt feederhouse you will need the tall feederhouse blocks for the 800/8000/8200 flex heads. Although there were some 800 heads with a lowering kit on the feederhouse so these heads could fit the low blocks.

If you do some searches there should be more info around. I put a kit on an R55 a few years ago, but now have an R66 that already came with it.
