rodeck 481 t oilpan gasket?

We are assembling an older Rodeck 481t with an Olson pan. The regular BBC gasket is to thin at the front and the rears. The one piece is better. Is there a different gasket that should be used as the step in the block is quite large .
Is there something else that should be done to prevent the gasket blowing out?
Thanks

 

Rodeck had their own gasgets that were thicker. I've been lookingfor over a year for them. For now I double-up stock BBC gasgets with silicone. GOOD LUCK !

 

I have a new set of Rodeck end seals and they are under lock and key until I figure out a way to make a mold or something along this line.

If you have an idea on how to remake these seals I would be happy to use my seals as the patterns and provide new seals for Rodeck users.

There is a pourable rubber that I used to make a seal on a turbo Harley Sportster project I worked on. I've been struggling finding it back.

 

Does anyone know the real reason for these uber thick, hard as a brick, pita to deal with seals? Why so dang thick?

The pans and covers haven't changed since the 60s.

 

I don't know but it reminds me of this...
I made an oil pan from scratch one time and used a truck block and a weiand front cover to copy from. When I went to put it on the actual motor (which had a Donovan frt cover) the radius on the cover was quite a bit different. Ticked me off I had worked so hard to match the radius, suppose that weiand frt cover was for a Rodeck?
