I am new to this forum.  I bought a 2 owner 1956 F100 truck with a 272 and 70k miles on the clock. Everything works fine exept that the lubrication for the rockarms on the passenger side is poor. Been told that this is very common on early y-blocks, caused by a design flaw, long oilchannel and old bearings. At time rumour says that external lubrication kits were sold to cure this

Engine runs very well otherwise and with so few miles on it I am hesitating to tear the motor out and rip it apart (wonderfully original truck). I got a tip to remove the passenger side head and drill a hole in the camshaft bearing to improve the oil flow.

This sounds a bit brutal but might work. Does anybody out there have any experience in this matter.

Thankful for any advice.
