im new to the form and new to the y block so im looking for any help i can get. i picked up a 64 ford pick up with a 292 y block and a 4speed. before going to look at the truck i was told that it had a rod knocking, but as soon as i heard it run i knew that it was the valves. i checked the lash on all the valves and set the lash at .19 and this fixed the knocking problem. while i had the covers off i realized that there was no oil. i did a little research and found that the y block is notorious for oiing problems. my questions are...

1.how do i check to see if my rocker shafts are on the right way? also if someone could explain how that assembly works. i dont understand how the oil is delivered to the rockers.

2. i found little pieces of metal by where the valve springs sit. what is that metal from? i read somewhere that this is a sighn that the motor was being ran with no oil getting to the top of the motor.

3. the rocker arms and shaft were heavily clogged with sledged up oil, i cleaned them a little bit and was wondering if its worth giving hem a deep clean or should just get a new set.

** im only looking to get a running motor. nothing special i just wanna be able to cruise it around once in a while**
