Has anyone tried them?Looking for something to hold a H/C (11-1) and future Nitrous shot.Talked to someone at Thunder and they do not recommend them for our cars <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />

 

I thought Jeff swore by these gaskets. Did you talk to him yet??

 

We've been talking. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Looking for more feedback.I know they will work on a reg. H/C car,but I don't know they will hold 550-600hp Nitrous car <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

What about the SCE copper gaskets?

 

Good thinking Don, but Fel Pro must offer race style composition gaskets. I will look into this and report.

 

For what reasons would you want to stay away from the multi-layer steel gaskets?

I use a 1041 Felpro (big bore) witout any problem. Unlike a stock gasket it has a fire ring and works well with nitrous. More important is to use a ARP head stud or bolt and torque cycle them several times before final installation.
