What is the compressed thickness of the factory headgasket, I can't seem to find it.

I was playing around with a compression ratio calculator to see what thickness of head gasket I would need to get back to around 8.4:1 compression with the arias pistons, which only come in a 9:1 version. I figured out that the total volume above the piston when a tdc was 66.5cc, so I put that in as the chamber volume of the head and set headgasket thickness, piston dish, and deck height as zero. I need the factory hg thickness so I can put the difference between it and the mhg thickness in the hg thickness box.

yeah, i had asked a similar Q about a month ago as i was trying to lower the CR of my NA pistons(9.2:1) Doc J helped me figure out > Greddy 3mm gives @ an 8.3:1 and the HKS 2mm gives @ 8.7:1
the factory HG thickness is 1mm. HTH
