Ok guys David Barton did my lifters. I was at his shop and he took them apart while I was there. There is really not much inside them. He told me sometimes he will put the spring back in the lifter sometimes no. I believe mine have nothing in them No spacers shims etc. I have a few sets of lifters I will try and take some apart and get some pics to share.

Not sure on my compression but cranking compression is 240 PSI
