has any one ever replaced the push in plugs to a 1/4 pipe plug? just looking for some tips. it says to use a 7/16 drill bit and then to use a pipe reamer, but i have read if you use a pipe reamer you need to use a 27-64 drill bit.
my holes were 7/16 from the factory i tapped one at the back of the block in the lifter galley that is straight up and down, but the plug does not go all the way in should it be flush? any tips would be appreciated. steve
