Firewall insulation

I am going to be pulling my engine for a rebuild and I want to address my sagging, dirty firewall insulation. There a lot of different products out there like Dynamat. Has anyone used them and how did they hold up to the heat? I don't want to spend a bunch of money on something and then have it falling off again.

Mt factory insulation caught fire over my twins so I cut it out and used a summit brand heat and sound mat similar to dynamat . Its been on there for 7 years with no problem . While I did the h/g I went ahead and did the rest of the firewall on drivers side with be cool mat and it hasn't stuck as well as the summit brand has.

I will check out the summit brand. I was reading the reviews for Dynamat knockoffs on Amazon and it seemed that most of them have adhesion troubles around heat. I need to do something with the hood insulation as well too. I am kind of surprised that it never caught fire for the previous owner. It has a C from the rocker cover melted into it. I put some more clips in it to hold it better but it is starting to sag down again.
