I know I'm right....
Heli's are almost a given in AL intakes. Especially the threads that get cycled, ie stat housings. Carb studs not so much as they dont get removed all that often. Stud the stat on still good threads and be done with it.
rethreading thermostat holes from 5/16 to 3/8 ?

I'd use these:
McMaster-Carr
Drill bit is an 'X', or .397 diameter. These won't back out like a coil will, and I've found them easier to install. Need to buy the matching staking tool though to set the keys. It's just a stepped punch, but having the right one is critical.
Thank you.
I stand by my previous advice.
Why drill the hole larger, then buy and install a coil, when you can simply drill a smaller hole and use the next size bolt?
The only thing I can think of that would preclude this is if there weren't enough clearance to get a wrench/socket on the head of the larger bolt.
But since we know Mopar went to 3/8 bolts later on, it's likely not an issue unless they redesigned the housing, making the bulb for the hose smaller.
