IMM Engines 408 build

I'm afraid to use low quality lifters now

I honestly don't think Easton lifters can be considered a low quality lifter when Brian has used them on many of his builds with success. He would be out of business really fast when he was using low quality stuff, and his reputation seems to be quite solid. So I guess it was bad luck for you.
Reminds me of the other thread with the lash caps falling out... turns out the OP turned the engine over, draining the lifters and then having issues... just sayin'.
