Yes they are regrinds, thus they have to remove material from the base circle, which results in needing lash pads to account for that.
As for install, I had a shop install them. Performance, I haven't gotten power pulls done yet with the new setup so all I can comment on would be partial throttle and idle. Idle has a very slight lope now but not bad. Throttle response still seems decent. So far I'm happy with them.

Sorry to bump this oldish thread..but how are these working out for you?
Also, what head gasket/head/bottom end setup are you using? I am curious because I will end up ~ 9.8ish:1 compression and am wondering what sort of lift I am safe in using..I think the 9mm lift like you have would be fine, but I am curious what your setup is for comparison..
