3020 specs and info

[69 4520]

Hi all
Working on 3020 gas early model. Two requests, head, rod and main bolt torque. Also the rod and main bearings have some lead or soft material next to crankshaft. What brand bearing has this nowadays. I don?t want just a steel shell. I have a book for 4000 series just not sure if specs a same. Thanks for your help.

My book says,head torque 115 ft lb,conn rods 85-95 ft lb,mains 150 ft lb.That is what jd service manuel says.

All bearings are made that way.
