Talking Head gasket specs

I searched thru the posts and I didn't see one that lists the stock specs for the head gasket. Thickness and bore size. Does anyone know if the Fel-Pro part # HS9473PT-1 comes with a MHG and what are the specs to that head gasket? I can't find any info on this.
Any help would be greatly appreciated.

Fel-Pro is similar to Toyota stock, not MHG. You can get MHG from Cometic, HKS, Titan Motor Sports. Depending on the current condition of your head and block will determine what thickness MHG you will need. Your best bet is to consult your machine shop. As for stock and daily use, Fel-Pro is good.

Does anyone know what the stock thickness of the head gasket is for a 91 turbo? Do you know how I can tell which bore thickness I have on my car?
The description on autoparts warehouse for the felpro kit states that it come with a multilayered metal head gasket.

1) Stock HG = 1.37mm compressed

2) Stock head = 116mm deck to valve cover surface

3) Stock block = 198.5mm from deck to main bearing saddle

If 2 and 3 are less that amount needs to be added to 1 to retain the stock compression ratio and squish/quench.

stock bore is 83mm
