Thanks all for the info. Al gave me the exact info I was looking for in a pm. I have talked to a lot of people about this and from what I have learned the important part of the bushings is the ability to make the oil hole in the bushing small for oil control per say and for covering the large hole in the lifter hole where it intersects the galley so you have more contact area around the lifter. It also will help keep oil pressure in the engine if a lifter is ejected if there is valve train damage, a broken rocker or such. I appreciate everyones advice as for now I know the direction I am going to take.
Thanks Greg S.
