Airsal base gaskets

how thick is the steel plate ?
usually a plate sandwiched between 2 gaskets is used to raise the cylinder/ports to make up for a stroked crank.
like 1.5 total thickness of all 3 pieces for +3mm crank, and 2mm for +4 crank
for a stock stroke crank I'd say just one of the green gaskets will suffice ?
maybe call whoever you bought them from or airsal themselves to confirm ?

No, as I mentioned above, it's to adjust port timing and squish clearance for a stroker crank. Raising or lowering the cylinder affects much more than just the compression.
If it were a head gasket, it would be more in the lines of compression. Squish would still need to be checked though. Is the one gasket just coated and has a steal "like" center ? Prob aluminum.
Like stated, id call n see what the deal is. Report back.

sound like the formula to raise the porting and head to allow for the extra 2mm upstroke of a +4mm crank.
The equation is wrong but the answer is correct. If you weren't using a stroker crank, you would still use a .5 mm gasket. So, with the .5 gasket and add 1.5 + .5 =2 mm for the 4 mm stroker you are in the ballpark, but still need to degree port timings and check squish.
