I have tried other gaskets, and I will say this one ranks the best. I have a set on my 95 dodge ram, and before, I would get a leak from other gaskets after a few years. I decided to try Remflex, and I have not had any leaks or issues with gasket in the last 6 years. I used them on my Charger with shorty headers, and when I took them off after 2 years to install long tubes, gaskets were perfect. You could see where the header smashed up against it and sealed. Nice and big thick gaskets that smash down and seal real nice around your headers to the block.
