Who has a roller lifter that basically just drops in ? I've heard stories of some that uncover the oil holes and some that you have to grind on the block to use. Are there any that work good that just drop right in. I have a kit to tube and peen my block, but I have heard some go right in and you dont have to do a thing. It will be a pretty big roller with 1.7 ex rockers and 1.8 int rockers. Thanks for any help
