I believe the Impy gasket is 0.029". If not, Cometic will make any thickness you want.

What's wrong with the .029 GM Impy gasket? I have run mine with 150 shot for a couple of years now, sometimes with detonation, and have yet to pop a headgasket.

I'm not quite understanding why you would post this? No one is saying there's anything wrong with those gaskets. Besides with detonation on a LT1 stock block the ring lands should be taken into consideration before the head gaskets...
