Gentlemen;
Heat or peolonged heat, is the issue. A stock 216 has neither so there not needed.
The stock 250 that guy had with 70,000 miles on it was a 'test engine' basicaly and this is why I didn't think they were worth the money there.
If he builds a 'turbo engine' then okay, as it will be a 'high rev' situation, probably with heavy valve springs.
Good luck to all.
