I decided to take a look at my lifters since I have the heads off.  All of them seem to be perfect with the exception of the intake and exhaust lifters on the number one cylinder.  They look perfect (body, roller, etc) but the roller does not roll perfectly smooth.  So they all will be sent to Comp to be rebuilt.  Good thing I kept that box. LOL

Since all the others seem fine I wonder if not enough oil pressure was getting to the front lifters on that bank to properly oil the roller at low rpm.  Wonder, Ponder  These have pressurized oiling to the roller bearings but were before the lifter band was modified.

This is after two years of street driving, a lot of idle time, and several trips to the track.  If it weren't for the two, I would just put them back in and run them while periodically keeping an eye on lash for another two years.

Just thought some of you would be curious how my lifters have held up on the street.

You did or did not modify the lifters for better oiling?

I did not modify the sides of the lifter band like the newer ones are.  Because it was the number one cylinder (cylinder 1 and 5 at the front will get the least oil if the lifter band is in the wrong place) I am suspicious not enough oil was getting to the front. 

That intake and exhaust lifter feel exactly the same.  One does not roll worse than the other.  It just feels like the bearings are starting to go.  Every other roller feels perfect.

How do you get more oil to that particular area?  Unfortunately, it being a 8.2 deck you cant just pull the intake and rotate the lifters like tires...

You can drill and tap the oil passages, then run tubing from the main feed to the front of the passages.

Doing more with less, or something like that.

I've got those in my 418, they were about a little over a year ago, so hopefully they are modified.

I would love to be able to do this along with spring oilers.
im glad they have held up this long though, as i am using these also, but i have the newer "fixed" ones.

Then you will likely not have this problem. 

I would determine the lifters had hit their limit of street use if it were two in random locations.  Being what it is leads me to believe there simply wasn't enough oil getting to them.  Like I said, the others seem perfectly fine to go back in for another two years.  Rollers roll smooth as silk and the bodies and rollers look great.

So when you get them back, will you modify the bodies?
Wonder what they will weigh before and after the clearancing?

Absolutely.  I don't plan to remove much metal.
