well im putitn a 99 b20z head on a b18 block

and i baught a OEM B20 headgasket

it just came in and i opened it…

from the edge of teh headgasket to the cylinder wall there is about this length - of space that metal is not covered

\*the dash is the amount of space…

No, this won’t work properly. You’ll have to get a PR4/ B18A headgasket.
