Cam & Timing Set Questions

I just recently broke in this 396/402 Chevy big block. Comp thumpr cam and lifters. Hydraulic flat tappet. During the last part of break in, it lost oil pressure and I shut it down. Drained the oil to find glitter in it. Tore it down and at least 8 lobes are on the way out and NONE of them look what I call "good". That's the end of flat tappet hydraulic for me. If this Ford 400 I just put in Gladys doesn't break in good, I'll send this .700 lift roller to Oregon and get it ground to a street roller and swap it in. I have my fingers crossed on the 400 though, because I put Crower Cam Saver lifters in it. So "we'll see".
