I have gone through half a dozen junkyard Vortec heads and they were all cracked in one spot or another so I really hope you bought brand new ones, otherwise I will bet you a case of 805 that at least one of yours is cracked

I've been thinking of closing the plug gap up 5 thousandths or so, just to see, but that's what the DUI spec calls for with their ignition. Heads definitely weren't cracked when they went on, and I doubt anything has changed. No problems that would indicate any issues with the heads.
Going to dial back the initial a bit today and see what happens. Been pretty busy with job interviews these last few days. Thread will be updated with results.
