Just a suggestion, not sure if its been mentioned, but if you intent on keeping the SOHC V6, I would change the spark plug holes. As they are now, they go straight through where the camshaft would be. My mom has a 2014 Odyssey with a J35Z8 and her coils are more off to the bottom of the valve cover. The Kashira currently has valve covers that look like its DOHC with SOHC cam gears and belt routing on the front. Just a little thing I thought I'd mention.
