For those who have done a restoration or completely stripped the interior, what did you use on the inside of the firewall for heat and soundproofing? I still have the stock blanket but I was thinking there has to be something better? If you did something different, did it perform better? I have researched Dynomat and equivalents and looked into Lizard skin and equivalents. I'm thinking the thickest Dynomat type stuff would be the best. Help me decide.
