plus DOHC and SOHC exhaust ports are spaced differently, making the turbo manifold a no go for fitment.

jesse did you ever see this block that you ordered? its pretty simple to tell the blocks apart, the DOHC has the engine code stamped by the bellhousing...the SOHC has the stamping (by stamping i mean what you normally see on honda's with the B18C or B16A3 etc etc) between the two middle exhaust ports about even with the deck.

good luck on the DOHC block, the SOHC block DOHC head thing greaser said it ran good but wasnt worth the trouble...the front covers and accessories suck.
