Patrickt thats just bad luck!
Run the same cam specs as Patricket has (converted to solid roller) and the lifters should make 100,000 miles.
Brent I'm the guy on the front row of the cheering section for solid rollers.
Lippy has invested a lot of money (by most standards) in his engine not to take a little time out to see if the lash has changed. I hardley consider checking the lash a couple times a year and giving the lifters a good inspection every 4 or 5 years (2000 miles a year) constant maintenance. Besides he will learn the engine and most likely enjoy it. It's my opinion and its free.
