Summit & Jegs sells them.
Tip:
Once you start adding a half inch or more spacer under the carb, do not slam the hood! . . . . . . . . . (yet)

And yes the box-end wrench is fine for half of those bolts.

Yup, I did see both versions at jegs and amazon. I ended up grabbing the one that had more buyer feedback. Meh, it's not brain surgery to go back in and swap it out if I still have carb boiling going on. And yes, I was careful to verify hood clearance.

All you need is a little sealant on the bottom 4-5 threads on the bolt. RTV doesn't "flake", it's made for sealing petroleum fluids, stays pliable and is easily removed. Both Ultra Black RTV and thread sealant with PTFE are Permatex products. Either will work.

So far so good. After sealing those 4 intake bolts in the center and putting everything back together with the carb spacer, I drove it up to my mom's place and back last night (100 mile round trip). No sign of any seepage now; and the carb seems to be staying cool better. Yeah, it's in the 20's out, but I checked on it ~20 min after parking it in the garage after the return trip. Seems to be all squared away.

Wood spacers can also be phenolic. Phenolic refers to a type of resin. Spacers can be 100% phenolic, think plastic, or a wood with phenolic sealing resins.

Ahh, when I read phenolic I was thinking bakelite.

Some are very similar to bakelite and some are similar to wood.

Bakelite is an early plastic product; no wood in it. Phenolics are usually some resin-impregnated fiberous material, which would include wood products.
