There is alway the screaming eagle options to retain warranty . Im pretty sure you mod the motor/ecu they are going to dx the whole powertrain with hd its always a crap shoot . I dont think it is that big of a deal turn the clock back to stock . Thats just my 2 cents .

New cam, new lifters. They don’t have to be premium, I used V-Thunder lifters when I changed the cam in my M8. No problem with them. I put Fueling lifters in my TwinCam and one failed immediately, so premium is no guarantee of quality.

Yes I would use the S&S anti-rotation devices. I wasn’t aware they were available when I changed cams or I would have used them. Yes you need to be cautious removing the bolts that retain them. I will be installing them when I do the big bore this winter.

If you go on Summit Racing’s website the choices for LS7 lifters are almost as confusing as the aftermarket choices for Harley. Did you just go with the Delcos?

Well i just pulled the cam chest apart on mine, another thing to note the crank sprocket is quite slack, as T-man found !
Depends how **** you want to be, he sells a tighter fit one but as with tappet cuffs just better quality items but no history of failures of stock items
