Default THICK Round Port header gaskets?

Can anyone recommend to me some very [B]thick[B] round port header gaskets? I have to run an engine diaper this year and mock fitting my new SM heads with a spare Moroso pan and round port headers is showing a issue. I need atleast enough room to be able to wrap the two tubes that are in contact with the diaper and to be able to drop the diaper for oil changes.

Rim Flex 12-002 header gaskets are thicker than 2 of the Fel Pro gaskets stacked. They work great.

You might be better off getting another flange to sandwich in there.

Another flange set will cost more than a set of remflex plus 2 sets of any other gaskets and he is already tight for room? Tom

DEI makes a header wrap that may work. If you can, make a belly pan and you will be so much more happy than fighting a diaper.

The good news for me is that on my mockup picture, I have neither head gaskets or exhaust gaskets. Just for giggles, I'm going to throw on a D-port head and a Hedman Hussler header that I have. It's too damn cold today though!!

My DRE diaper has a kevlar shield sewn in. It literally lays on some of my tubes with no problems.
