mstngjoe, I will run either style because the lifters will determine the cam. I am looking for roller lifters that will allow me to install them at my house w/o having to machine the block. If I have to do something like drill and tap a couple of holes, then no problem, but if I have to take the whole engine out then no dice. If the roller lifters are prone to cause problems, then I may decide against them. Any help will be appreciated.
