Well, duhoh, I was installing my new SBC intake with my new ARP stainless 12pt bolts. I just had the heads done, and apparently the media blasting of them damaged the first few threads. All were difficult to screw in. Frustrated, as the gaskets and RTV were already in place, I backed out the bolts that were in and removed the intake in order to tap the holes. One of my bolts was stuck, and the head snapped off. I drilled it for an easy out, that snapped off as well. Apparently it's in there pretty damn tight. Now, I already have the engine all together, and I don't want to remove the head and bring it back in. The bolt is on the passenger side on the firewall side of the exhaust crossover in the middle.

Will I be okay with 5 of 6 bolts on the one side of the intake? Will it seal okay? I have new gaskets and the remaining bolts were torqued properly in sequence to 20ft-lbs.

Will this work?

Which one was it? The two on each corner have to seal water. I've had a lot of trouble sealing the intake to the heads where as they would suck air from the lifter valley. That was with all bolts in place. Not meaning to discourage you.

It's in the middle, next to the exhaust crossover. It's on a new performer rpm air gap. I smeared a thin band of RTV Black around each water passage. I also used a bead of it on the ends instead of the rubber seals, per Edelbrock's inx and my machinists recommendation.

well, the newer Vortec heads don't even have bolts in the middle, and mine doesn't leak. i guess if you are gonna do without any of the bolts, the middle would be the place to do it. of course, my Vortecs don't have a heat crossover in them, so there isn't any extra heat in the middle like on the older style heads- so you might warp the intake a bit without the bolt.
it might be best to pull the head off and go right back to the machinist and tell them you want it fixed for free, since it was them that screwed up the threads in the first place. of course, they might counter that you were the idiot that tried to screw it together anyways....

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

Yeah, my machinist said I could bring it in, but for a lot of extra effort, he didn't think it'd hurt to be missing that bolt. I still have a bolt on the other side of the crossover. Also, my crossover is blocked by the gasket, and my Performer RPM Air Gap manifold doesn't even have a provision for the crossover, so that's pretty much unused.

You make a good point about the newer Vortech style heads not even having those bolts That makes me feel better about it.

Well if I had paid attention you said which bolt it was to start with. Just me but I'd be tempted to give it a try. Keep in mind the symptoms of a vacuum leak, as that would be the problem if it doesn't seal. Hang on to the head of that bolt so you can use it for cosmetic purposes if it works.

In my opinion, if it is worth doing, it is worth doing right. It may or may not work but either way it isn't right. JMO

I kept the bolt head for just that purpose.

I'm hoping for the best. I'll give it the carb cleaner spray test once it's running...if I get it started.

Just remember not to be worrying about a vacuum leak while your breaking in the cam. Keep it running (if it will) and check it out later. The vaccum leak could come from the inside and that carb spray test wouldn't work. However in most cases it will suck oil and you may have some smoke. If that's the case after it's run awhile you may be able to see oil puddled in the bottom of the intake when you remove the carb.

deerhunter, you make an excellent point as well.

I hear you, but I've struggled with this engine for so many weeks now, I've about had it. All from some lame-*** who put the heads together like a complete jackass and I've got this far, I don't have the energy to take it apart. I'm pretty anal, so I've not touched it for a week due to the frustration. I just want to get it running and break in the cam since I've got this far. Once it bothers me enough, or if I have a vacuum leak that would move up the timeframe, I'll pull the head and have it fixed...but that sounds like a better winter project if it doesn't have a vacuum leak. I've had it apart since June, so I'd like to drive it for a few weeks before the snow sets in up here in lovely MN.

I drove it last night, and am still doing some tuning, but it seems to run fine. I can't really tell if there is a vacuum leak. If there is, it's not noticeable....it doesn't idle high as far as I can tell. I guess I'll just see how it goes, if it's hurting anything, I'm not aware of it.

Hear no evil...see no evil, right? Too bad I'm too anal to live by that!!

Yeah if it was me .. I would have to get what's left of the bolt out of there. It would bother me plenty to run an engine like that.. Look it's your money but if it were mine it would be fixed. It would hurt my head worrying about it all the time. I like to make sure my rides are bullet-proof.
