I know the consensus says not to, but I find it so hard to believe that the austempered cast cores can really be that bad if Lunati, Comp Cams etc are selling so many of them. It seems like you'd hear about a lot more failures.
I bought and am about to install a Lunati Voodoo hyd roller with Lunati roller lifters in my Gen VI 454. 241/249 @.050 and .625/.625 lift. (edit) 377 rate Lunati springs. Maybe in two years I'll be eating crow, but I just don't think so/hope not...
