Dragsix That is interesting on your setup,best way to find out stuff is put it together and try it !! You do that regularly !! Have been on the hunt for lifters they are expensive. Have you had much experience with reground lifters ?? My current Kwik-way valve machine doesn't do lifters,aa friend with a sioux machine may be able to have to check that. Checked with Ed Iskendarian he still offers 235/261 stuff but big name big price.
