Re: Just finished motor rebuild......head gasket issue Yup she is driving just fine now <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> . I got to put a few miles on her tonight. She feels pretty good below 4500.
It is too hard to not get into it after 6 weeks of not driving her <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
I will get some new dyno numbers by the middle of next week with the new F1 cam.

Re: Just finished motor rebuild......head gasket issue Both of the gaskets looked fine as did the block surface and the head surface. I really don't know exactly what the problem was with them.
As soon as the stock gaskets went on the car ran perfect. Have you guys had any problems like that before with the Cometics?

Re: Just finished motor rebuild......head gasket issue I thought it was called the FU cam? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
Glad you got it running. Time to put some miles on it and hit the track.

Re: Just finished motor rebuild......head gasket issue No probs with the Cometics here, but I have stock heads, no milling.. Maybe it was your milling with the steel gaskets?
What lube did you use on the studs into the block? Moly or Motor Oil? TQ spec match? Mabe it wanted a bit more TQ than listed spec?

Re: Just finished motor rebuild......head gasket issue I used a Moly lube on the bolts when I installed them.
It was not the torque spec that caused the issue. Like I said before I have installed multiple sets of these gaskets and never had this issue before. Most of the previous installs were using stock head bolts which were torqued to 65 ft/lbs.
I was using the ARP's torqued to 75 ft/lbs. I only torqued the stock head gaskets back to 70 ft/lbs and still all is well.........

Re: Just finished motor rebuild......head gasket issue Glad all is well.
So do you think it was milling imperfections and the steel gasket surface mating that caused the issue?

Re: Just finished motor rebuild......head gasket issue Damn right! <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />
Not sure it matters, the bolts probably stretch past a certain TQ spec. Max TQ they can take I assume without breaking and stretching some. More is better. He followed the GM spec for years but believes it is BS. I'm not gonna go into it any more. Do whatcha want. Def be afraid of doing something differnt and not following the GM bible. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Just finished motor rebuild......head gasket issue I am not sure what exactly was causing it to leak. I am just glad that it is not leaking now <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
I will have some dyno numbers at the end of the week, with the MT1 S2 heads and the new Fastech F1 cam, and will prolly have some new track times in the next few weeks........
