Default Head gaskets blowing out

What kind of head gaskets won't blow out under boost? I need to know since mine just went. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

Call them at http://www.cometic.com/

Ask for good boost gaskets. I believe the 'HP' series are the best.

They are expensive...200 bux for the pair but they are reuseable!!! I have used mine 3 times now. I just clean them with gas or carb cleaner and lightly coat them with copper spray <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Yep...I just installed my new 77cc LS6 Heads with .065" Cometic Gaskets. Cometic recommended Copper Coating for Turbo Applications.

I used Cometics because I needed .065" of thickness to drop my CR below 9:1. and because LPE uses them on their 427 TT and Cometic claim they Copper Coat them.

I am running 77cc LS6 Stage II Heads with Comp Hardened Push Rods and Rev 1116 Valve Springs.

I am hoping that I did not mess anything up using Copper Coat on my new Cometic Gaskets...I was told by what I would consider a reliable source that LPE uses Copper Coat on Cometics. I called Cometic again this morning and the guy told me he doesn't recommend it.
