Is it possible to put a DOHC Head on a SOHC Block? I was reading the SOHC to DOHC Engine Swap but I do no not want to swap the whole motor out. So is the head interchangeable?
It will just increase your compression. Shouldn't have any clearance issues though. Just increase compression which if you want to turbo, I wouldn't do it.
Yes they are interchangeable and it will up the compression ratio.
Stock compression ratio for a SOHC is 9.8:1. Swapping over a DOHC head and leaving the SOHC pistons in the block would drop the compression to 9.3:1, ideal for a turbo.

Really? I heard over on the .org that it would raise the compression. Oh well! lol sry for the wrong information.

Look at it this way, the SOHC head has higher compression than the DOHC head. The DOHC pistons have a higher compression than the SOHC pistons. DOHC head with SOHC pistons equals lower compression.
