Wanted BBC early roller cam/lifters

[SS69chevelle]

Thanks for the info guys. The odd thing is the lifter bores are grooved on the top side of each bore from top to bottom. It is also a considerable groove and I'm concerned about oil pressuse if they aren't bushed or the grooves filled. Honestly, I don't expect to find any lifters but thought I would take a chance and put the info request out to some of the best forums to see if anyone had knowledge to share. I continually learn alot from the forums here and at Team Chevelle. thanks again for the comments. Andy
