if they are metric I was going to tap to 5/16.
Ill cut em real close only so as to only use one washer for a bit cleaner look I got the Fox style CAI kit in red and Im going to hop on this swap in the AM, and see if everything fits and if the hype is as advertised 
Cleaner engine bay -with a valve cover change- and a slightly bigger TB... we'll see. After this I feel the need to Tweec, then the 347 as a winter project..... then ? GIMME FUEL GIMME FIRE GIMME THAT WHICH I DESIRE!!I never believe the hype anymore...
I just do it and get my own synopsis of it...
Part throttle feel may change, but go to the track, or better yet, the dyno to see if there is a difference...
I imagine if near stock, you shoudn't see any power difference...
JUST a FYI they would be 5/16 X 18 X 2.25 PERFECT.I believe the size for throttle body studs is– 5/16-18
Let me know the length you need...I'm curious
JUST a FYI they would be 5/16 X 18 X 2.25 PERFECT.
I thought about using bolts too but
My ride isnt show material so I said what the heck.
