new to honda tech, i recently purchased an EJ8 coupe with a B series swap. Motor has a blown head gasket, i went to look fro the engine code to figure out which it is and the PO ground the engine code off the block. no Idea why. the numbers below are 2338660.

i can take any photos needed to help identify this block. To me looks like a B20 head and valve cover. its probably safe to assume its a B20 but im doing head gasket/head studs/exhuast studs/exhaust manifold gasket. all of those seem universal except the head gasket, which should? vary by block IIRC.

any input is appreciated, hoping to get this civic up and going quickly. the small amount i drove it it was a fun little car.
