yeah dude, you just need a THICK bead of silicon to seal that gap. the gap is normal because there is supposed to be a cork or rubber gasket that goes in there, but those gaskets SUUUUUCK - so throw them away (which you did already obviously) and just use the thick bead of silicon

 

If you only have a space at the front and the rear of the manifold, and no space between the manifold and the head, then I would just put a heavy application of RTV on the ends of the manifold and bolt that sucker down.

It is just hard to tell exactly what your situation is from the pictures. Bolt that thing down, and post new pictures showing the joint where the manifold and the heads come together.

 

Go look at this link - http://www.mustangsteve.com/intake.html

it shows you the bead of silicone that you should be putting down at both the front and rear of the valley. BTW - make sure that you put a thin bead of silicone on the intake manifold itself at the front and back so that when you lower the intake into place the thick silicone bead meets up with the thin bead of silicone on the intake manifold. This will give it something tacky to meet up with and will guarantee a better seal instead of the thick bead meeting up with bare cold aluminum. Cleaning everything off REALLY well before putting the silicone on is important too. Also make sure to use some studs inserted into the heads toguide the intake manifold downward into the correct location. You DON'T want to try and eyeball it as I can guarantee it will slide/move around before you get it into the correct location. Just make some 4-5" long studs with all-threadand put 4 of them in the heads to help find the correct location. Works very well if the motor is still in the car as you are leaning over it and usually off a little bit.I use this same method for all my intake manifold installations and all have sealed up perfectly with no leaks. BTW- neveruse the front & rear cork seals that come with the kit.

OH and most importantly - you don't want to use that blower - you should send it to me instead...

 

an intake leak on a blown car could be interesting... a real flamethrower... [sm=badbadbad.gif]

 

dont worry guys i got it done... the gap is no more...... a quick question why dont you use the gasket that come for that gap? well my kit didnt have one but still.... and 68SCode4speed you can have the blower for the right price!!!.. thanks guys for the help.... for being my first resto/engine build i think im doing pretty good

thanks

 

Leaks like crazy after a while.
