In order to install the sleeves for the 39gr. lifters in my 2270, it appears that the original lifter bores must be spot-faced in order for the sleeves to press in correctly as the original lifter bores do not terminate with a flat facing.

What depth should the original lifter bores be spot-faced before pressing in the new sleeves? Anyone here done this before, or know someone who has with positive results?

There is a picture on page 8 in the engine gallery that illustrates what I mean.


Thanks
