My concern is if it does not matter or if they were facing wrong to begin with, and I reinstall them with one turned 180 degrees will that be the same as getting one back in the wrong hole and cause galling due to the roller now turning opposite what it was on the cam.

I know but when I removed them and set them out the way they came out they rolled on the table. I know I have them back in the correct holes but they are either just like they came out or turned 180 if they are turned I didn't know if that would cause issues such as galling on the cam because the roller would now be turning the opposite direction and may not be sitting on the cam the way it was worn togather

I can't afford to lose an engine because of this mistake

What is your opinion?
Expert:  Tim's Auto Repair replied 1 year ago.

in my opinion...they do need to roll the same as they did before..because the cam already has the pattern

Expert:  Tim's Auto Repair replied 1 year ago.

but as for the oil holes it doesnt matter

Expert:  Tim's Auto Repair replied 1 year ago.

the only other thing you could do is install new lifters

Expert:  Tim's Auto Repair replied 1 year ago.

in my off the record opinion,i think they will be fine sense these are roller..

Expert:  Tim's Auto Repair replied 1 year ago.

there s no way of know if you have them 180deg off now or not sense they were moved,,but,i dont see that it would hurt anything

thanks

Customer: replied 1 year ago.
OK I will try to turn them per the wear marks on the sides, one more question which way does this engine normally rotate? Would it ensure me no problems if I installed a new set of lifters on the old cams? Or is it still rule of thumb not to replace them w/o replacing the cam?
Expert:  Tim's Auto Repair replied 1 year ago.

the engine turns clock wise

Expert:  Tim's Auto Repair replied 1 year ago.

the new lifters will work just fine with the old cams

Expert:  Tim's Auto Repair replied 1 year ago.

again,off the record,i think the old lifters will be fine,,but if they worry you,all you can do is install new lifters

Customer: replied 1 year ago.
OK thank you for your help. This whole deal worries me but as you said there's know way to tell how they were, the only thing I know is there was more wear on the front side of the lifters than the rear so if it turns clockwise that makes sense as you would have more side thrust on the lifter as the cam opens the valve than you would have when the lifter comes off the lobe.

I say front side meaning toward the front of vehicle
Expert:  Tim's Auto Repair replied 1 year ago.

yes the front is the front of vehicle
