Intake runner size
 

Yesterday I pulled the plenum(special thank you to whoever loctited the Air horn torx bolts>:(

While I was in there I took a shot of the bottom of the IH to show how much the ports neck down. 31.11mm in this shot, the plenum and tops of the IH were all 33+

While I was in there I replaced thecoils with Autozone(Wells) coils, also pulled the started and found and extra plenum bolt and a 1/4" socket. Breather hoses replaced as well, as they were rock hard!
