I have to wonder if Toyota had the MR / FWD mounting in mind when they (or Yamaha) designed the 4A-GE. I have one each of the big port heads and noticed this difference.

I've yet to see a Toyota application that uses that mount...........

"Building" the intake side - blending the seat, bowl, and port Wink
