Got the shipping confirmation on my distributor base and it should be delivered tomorrow. Hoping to have better news then.

Were the rollers flatspotted on these 305s, or are you talking about flat tappet engines? I've personally never seen a roller cam wear, but I'd have to imagine the only way it could is if the rollers were trashed.

I have to wonder how many of those failing LS engine are being filled with oil that's only suitable to use for starting a fire.

I'm going to be pulling the intake to re-seal the ends with better RTV than I used last time, so I might just put a dial indicator on the lifters and see if I've lost anything off the lobes.
