I picked up a set of AR rocker shafts, stands last month. We found that the stand will actually lift off the head with high spring pressures. You can insert a feeler gage under them! They also went thru changes. Some of the stands are different, half the shaft slides into the stand and not bolted down thru the stand. There is a counter sunk screw that bolts the stand to the head underneath.....I think.
My buddy has intakes for the AR. He may trade you for a blower manifold if you have one?. Here is another odd item I saw. He has 2 sets of AR rocker covers. One set uses only 4 bolts to hold it down!!
Wanted:
Blower manifold for the 429 Boss
Rocker covers for the cast iron ford boss hemi heads. They have the letters F O R D cast into them.
