What head gasket you guys running at 30-40psi? I was running a cometic at first, then changed to a copper. Took it to the dyno and at 30psi it lifted or blew, I think just lifted though. Anyone with experience with the copper? Pretty sure im suppose to retorch after a while but didnt think after 6 dyno pulls. Any help would be appreciated.

Thanks

 

im running a standard cometic .030 on 40psi and some spray

 

I use only golden eagle. They are factory gaskets resized. I would look at your timing map- 9 times out of 10 timing causes headgasket failure.

 

golden eagle -- copper o-rings in the block -- no problems

 

Stock OEM Honda

 

Golden Eagle HG, headstuds and copper O-ring

 

I have a aebs o-ringed block. Has or is anyone running a copper? I may have to try that golden eagle this time! The cometic was pretty good to me also though.

 

stock with copper orings. Nothing beats it.

 

just out of curiosity, what makes people think the head "lifts"? is there a sign or do they just feel badass thinking they make so much power that the head magically wants to fly away? no offense to you OP.

 

I would look into your tune. That is probably causing your headgasket issues. I run a cometic and have no issues at all with it.

 

I run a cometic but with a copper you should use hymor, I think to is it. I used to retorque it after the car came up to temp or after a couple of pulls or runs.

 

pretty much the same one, but this time thought I would go with a copper? Wish I didnt now. Did not have any issues with to cometic, couple people I know did over time though. This is my first HG problem so I thought I would ask some questions.

 

Cometic on our honda, copper on our sunfire

 

any problems with the copper? Ever has my problem? Do I need to retorch this soon?

Golden eagle hg here at 85mm, no orings, no issues.......yet

From what I've researched Honda doesnt have enough clamping force to smash the copper gasket to seal correctly. Having only 10 bolts/studs are not enough.
I know that I've tryed them years ago and never had any luck with them even N/A. I had stainless wire with a reciever groove and all kinds of sealers. Nothing worked.

 

same here

 

used all goldeneagle stuff before and switch to aebs on a rebuild and had nothing but issues.now im back to goldeneagle everything-block,headstuds,mainstuds,and gasket

 

I used copper with an o-ring and it worked great. I have even reused them.

 

that makes sence, probably will not even try to re-torque it, just go back to cometic, thats what i get for trying something new, just got the damn thing back together to. lol

 

Did you have to re-torque it? Any certian things im missing here? I would have thought more people run them or have tried. What made you change?

 

ive gone back and forth between OEM and cometic gaskets with arp studs and have come to the conclusion it doesnt matter as long as the tune is good, and more importantly the machining of the block and head are good. 90% of the time i have seen head gasket issues has been a result of shitty sleeve jobs. or people hot lapping their cars with crap radiators, radiator fans, and having coolant temps that are through the roof.

missfires are brutal on the head gasket too.
