318, 1985-1989? or 1985-1990? 85-91? a few quick ?'s

Do these engines have hydraulic roller camshafts?
Any important differences (besides oiling and rockershafts) between the engines? I believe the camshaft snout is somehow different but I don't remember.
Didn't someone here mention that using a J head on a roller 1988-1991 360 engine had issues with the pushrod pinch?
Do both 5.2 and 5.9 magnums use 360 oil pans or no?
many thanks

85-91 are HR and 9.2:1.

67-69 are also 9.2:1 but not likely to be accurate, at least not as much as the 85-91.

Adapters for the short nose cams that came on the TBI engines, do that you can put the eccentric on for the manual fuel pump.
