yes that is standard, hence they can be used in 2.1/2.2 builds at 87mm.

tnx.. hg thickness is 1,1mm , my head returned from headwork with port and polish and skimed for maybe 0.2mm

my plan is cuting valve reliefs for about 1,2 mm or 1.5mm deper max (if possible so much?) for valve to piston clearance

will compression of an engine be over 11:1 ?

stock oem gasket is 1.2mm, pistons can be safely machined +1mm, bridgecraft engineering can do it.

 

or get a 1.4mm repair gasket.
