[QUOTE="golfer, post: 451846, member: 266"] we quit using Cometics years ago...very mixed results regardless of impeccable surface finish & flatness... basically...any build expected to make >40psi gets fire rings..if we're going to stand behind the work. As far as driving on stock gskts & H11's (over 40-45psi)...I wouldn't know what to say, other than conservative driving for 10k miles...retorque...another few thousand...retorque...then cross your fingers when you lay into it...
