Headgasket selection
I stumbled across this today trying to find out exactly what gasket I need for my build. http://www.aagaskets.com.au/files/FLO9NZM6UW/Nissan%20SR20%20Head%20Gaskets.pdf

But, I'm still trying to figure it out. U13 block with a highport 53J head. From what I can tell I need BT050W-Sr20de C23.

Is this correct? Or does anyone have the part # that I need for an MLS preferably a Cometic?

And, is .030 the oem thickness?

no i think the oem thickness is .070 or .090, cant remember but im leaning towards .090

Still haven't found this anyone know for sure??

well, finally found this but I'd still like to be sure about it, I guess lower compression won't hurt a thing when I start hitting the BIG boost...
