Help! Intake manifold won't fit!

So I went with the Felpro roll of gasket material (thanks mderoy340!) and made my own. Fits perfectly now!! My last problem is the old temp sensor is way too small (npt maybe 1/8?) for the Performer hole (3/8 npt). Is there a different temp sensor I can use or should I get a reducer? Also the taller throttle cable bracket worked perfectly when I installed it. Thanks for everyones help!
Just get a reducer at the hardware store. 1/8 NPT for oem sender.
