I was asking specifically for my plans, which are a Hemi. I kind of think that the theory/logic is the same. The shop that was for a roller told me that he uses nothing but Comp Cams CC829 tappets and has never had an issue with them. I have talked to a few guys that use the same lifters and other than sending them back every 10000 miles for an inspection have never had an issue with either the tappets or the higher spring pressure. I fully understnd that there is more than one way to skin a cat. But if given the choice of, in my case with a mechanical roller, a few lash adjustments and some occasional maintenance or being faced with what happened to you, I will take the maintenance. I will not be putting 50k miles on my car a year, so it is not like the maintenance will be an issue. If you were to put a flat tappet cam in there and have it go flat again, you will be out an additional $300 or whatever for the new cam and lifters, plus the nightmare of the filings everywhere. Is the roller set-up really going to be that much more?
