Alright so i just had my b16 sleeved, new pistons, rods, etc... Bored to 81.5mm. Was told the stock headgasket will work. Set stock headgasket on block and is pretty much flush with inside of cylinder walls. Is this ok to use or no. Thanks for any help

 

my opionon if you did that much work to the block..might as well upgrade it. that 200 head gasket can save u headache and more $$ down the road. my 2 cents

 

Pretty sure that there is a 81.5mm specific head gasket.
