Intake bolts
Reinstalling a Elderbrock intake and I'd like to install washers. A different style bolt with a smaller head also. Most bolts in intake kits are only 1" which is a bit short I believe. Will the 1" be enough? The ones I removed are 1.25 SS with a regular hex head. A few are almost impossible to get torqued down.

Regular hardware store stuff is 1 and 1.5 inch. Most will have Allen head also. You want 12-point you need to find a fastener place. Another option is buy longer, thread nut on the bolt, and cut it to exact length you want. Removing nut cleans up the end of the thread. Aftermarket intake implies originality isn't your first priority. Standard cheap hardware store bolts are just fine for intake manifolds, carbs, etc. DON'T use them in connecting rods and flywheels...

Those appear to be flanged-head bolts. What's the purpose of the added washer?

Those ARP are pretty and pricey. I'm needing something with a washer and a smaller head one in particular is nearly impossible to tighten when snugged up. I've seen kits like I want but only 1 inch in length. I was just wondering what others are using in this situation

Buy a single Allen head bolt for the hard one. Or 12...

A good flat washer under them. If too big diameter. Bolt washer to a 3/8 bolt. Chuck bolt in a drill. Fire up a grinder. Bench, makita 4-1/2, whatever.spin washer and put it against the grind wheel. Not a real precise surface grinder, but it'll make a washer the size you want.

I like the smaller heads with a washer like Summit sells. they usually come in a kit. the edelbrocks and other aftermarket intakes have larger holes than stock, I assume for variation in head angle if they've been milled or block decked, at least that's my theory. factory bolts don't tend to work as well without a washer and those middle ones are a pain to tighten unless you get a reduced head or allen head style.
don't forget sealant so they don't weep oil.

Are those just split-lock washers? If so, that makes sense. From the photo, it looks like they are just flat washers, which made no sense to me.
[Split washers will keep the bolt in place; flat washers in that application would do nothing for the joint.]

BTW......these stainless ARP intake bolts are the only ones I will use......they are mandatory on a lower singe plane intake.......no way to get a wrench on normal bolt.
Oh.....and make sure you use a little PTFE on the bolts too for the ones that are not blind......

To get a proper cinch without digging into the intake metal......the "flange" bolt is not really such.......it is just a smaller head for extra access in tight areas.......
