I was doing my leak down test and barelly got started when's I heard air gasping out threw the gasket for the reed cage I tried to check the torque on the screws and they all just kept spinning then one broke . Lukily there was enough left for me to grab it with vice grips. So I used a same size tap and tried to clean up the threads did not want to go any bigger afraid I might break the screw housing so my question should I go get some threaded dowls and permanent lock tight then just use nuts to secure the intake or use stainless screws and hope my rethred holds I think I only got one shot at this if I mess around to Michele I know I'll break something so witch one do you guys think is the best
intake threads are shot

I prefer bolts in the intake window simply because I'd be afraid of locking studs in there and messing up the threads and not being able to get it back out (not a fan of studs on the exhaust side either 
)
Personally, I'd get a M6 x 1.0 helicoil kit and replace those blown threads with new steel lined threads.

Is that some sort of threaded sleeve? Where might I find one? I would imagine it requires. A bit of drilling ?
. I'm really only worried about the two bottom its been my kinda Luck to break small things like that. If I do break it what would be the best way to fix it?
It's actually a diamond shaped coil of wire. You drill the original threads out and then retap using a special sized tap. The diamond shaped coil of wire threads into these new threads and the inside of the diamond shaped wire coil ends up being M6 x 1.0 (or whatever size helicoil kit you purchase, M6 x 1.0 just happens to be the correct size for the intake manifold bolts).
Helicoil kits come with a handful of spiral coils, the tap, and combination tap handle installation tool.

That method will work great on the upper bolts but there's very little meat around the lower bolt holes AND the intake manifold is nearly a perfect fit hole which means you'll need to drill it for the oversize bolt which means it'll only work well on your quad and if you get a new one, you'll need to overdrill that one too.
Ok think I'm gonna do that. Whatever it takes to keel from having to replace the cylynder because of a little screw
In my experience with Helicoils, the hole you drill and tap to fit them, is just about the same size as drilling and tapping for a new bolt.
I always shy away from using Helicoils where a bolt will be often removed, as I have known them to come out.
Also it is not a good ide to Loctite a bolt into a hole repaired with a Helicoil, for obvious reasons.
Helicoils are very good to use when replacing studs and bolts when correct and matching tensions must be observed, Eg: head bolts.

I've personally never had an issue with helicoils having trouble after installation but I have heard of other folks having problems before. The way I see it, if I never used anything anyone else has ever had a problem with before, I'd never do anything, ever.

That is worthy of a sig quote.I:II:II:I
I have had some problems with Helicoils coming out of Alum and tearing a very big hole (I should say ******* big hole, but I dont swear).
I only ever use them when all other options run out.
So what's a better option where the hole around the busted threads is thin (as in the lower intake window holes) and the thing they go into has a certain size hole and not much extra?
So looks like I didn't need either I used new bolts and the featured must have worked. Got them all to torque down and be airtight. Freaking mirriacle only bad is now I'm wondering if my reeds are bad due to engine performance so may have to take it all apart again
A better option is to stud the hole and loctite it in, and then use a nut.
I realise this is not always an option, as there are applications where one can just not use it.
On the lower intake window holes, this is a pain as stated earlier, as one has to enlarge holes in other components so the stud can be accomodated, and fitment becomes difficult. It makes fitment fiddly but not impossible.
Helicoils are a very good to replace stripped out threads, but I shy away from using them where there is little meat around the hole, and the fastener may have to often be removed.
I have experienced Helicoils backing out and tearing large holes.
