Toss my name in on the side of not running steel in a race motor, particularly a stock block one. Not even for free. I have used a few different brands with no issues. I ppan on replacing mine at 150-200 passes. Only as a maintenance issue, not becuase I believe they are done, as they will go in a street motor as the old ones before them have.
