I can totally tell you been building race motors for 20years like you said....any grown man would call someone gay boy
"Hey blackmagic94(nice name by the way gay boy"
I'm done with this kid.
MLS...the layers is what give them better sealing ability.
Aluminum expands and contracts 1.7 times faster than steel, this causes tremendous shearing forces between the Aluminum head and the steel block attacking the structure of the gasket, trying to actually rip the gasket apart as the temperatures move up and down. In the past Copper O-ring gaskets were the solution to big power on multi material engines, today we achieve superb sealing and longevity that is unheard of even with the traditional Copper Gaskets and especially composite gasket materials. These gaskets will not work harden, they will not push between cylinders like a convention composite gasket and if installed and handled correctly they can be re-used. The unique design and the properties of the Stainless Steel material promotes even loading for a superior seal, reduced brindling in the head and reduced bore distortion. Copper gaskets are prone to work hardening in stressed areas causing hard spots and uneven tork loads which will eventually cause distortion of the bores and the cylinder head itself, these issues are resolved with the Cometic MLS Head Gaskets.
Just my opinion and 99% everyone elses...we will run cometics. I ran lockwires...been there done that, moved onto bigger/better things....you should try expanding your horizons, new technology is a b i t c h huh.....its not all about cubic inch these days.
