They held up well. They weren't nearly as fragile as some thought.

Im running a 307 window right now. Im only a little nervous as Im not making big power , but in the beginning I was crossing finish line at 7000 and was waiting for kaboom. Now things are more inline and rpm's are at 6300. I feel allot better now. Oil looks great and pressure is still the same.
