I remember talking about this before however i didnt find anything that answered this exactly with search im sure its in there somewhere but its a pretty straightforward question and maybe someone has more to add than before. Which layer do I use top or bottom ? How much does this really raise compression ? I will mic it when i get the gasket and calculate the CR

 

I don't know about a 1layer.......2 layer, and remove the middle. I believe its about .2-.25:1

 

hmm i thought ppl were telling me 1 layer a few months back

 

yeah the middle layer is the thickest. u would wanna keep the top and bottom. i have the middle taken out of mine. its been like that for 4 years.

You probably remember reading that they REMOVED 1 layer......
I did a 2 layer and flat valves in my JDM H22A to push that 11:1cr mark.

corey jacobs just ran one of the outer layers on his H1 car, however that motor had a blown headgasket later on.

 

i have run one layer in several dd motors w/o any problems. the only difference between the top and bottom layer is the "up" on the upper layer. one purpose for the middle layer is to give the upper and lower layers a smooth/flat surface to seal against. it is not a good idea to remove only the middle layer because the raised areas of the top and bottom layer are designed to seal against a flat surface. this is why you can use one outer layer, because the flat surface of the head replaces the flat surface of the middle layer.

i would recommend using only one outer layer. this is the way it is done time and time again w/o any problems resulting. btw, the spoon single layer headgasket is the bottom layer of the oem gasket repackaged.

wow.. thats interesting right there..

 

so just either top or bottom it doesnt matter which one correct

 

on my engine, i pulled the middle layer, and then copper sprayed between the two, and installed it that way. has held up for a few years as well.

yeah, i learned a little about these h series motors from changing the oil in my civic all by myself

 

ok im going to be running only the bottom layer. It is designed to seal the the underside of it (the block), should I leave it like that or flip it or does it not matter either way should work ?

well hell thats like getting a buy 1 get one free on headgaskets. lol

 

so no worries about piston to head clearance when you do that?

 

no.
