Updated!! FAST intake fits like SH!T...whats everyone do to fix this???

Can you take a pic of the manifold to cylinder head from the front of the engine looking back to the back of the head.
Looking to see if their is a problem that an angle milling will correct in the intake side of the cylinder heads.
What has been done to the engine any machine work to the block.
Something looks way out of wack I dont think modifying the intake ports is the answer.

Be glad that the lip isn't reversed! With the lip being in front of the airflow it will create an air pocket there and flow right over that edge on the head, but if the intake flange was overhanging the head flange then it would create turbulance in the intake port cause the air would then tumble. That does suck though. Looks like that intake is ported already, would an unported intake be this bad?

Ok by the looks of it the heads might have been angle milled thus causing the intake manifold side to sit higher than the exhaust side in affect rolling the valve head perpendicular to the piston changing the valve angle to less than the original 13*.
Were the heads angle milled?
Were the heads angle milled?

Can you measure the base of the head to the bottom of the intake port and give me the measurement. I have a set of Trick Flow and ETP heads here i can use as a comparison as well as multiple stockers to see what the ones i have measure up to see if its in the head or not. I also have a 92 here i will mate up and check the measurements on also.

looks like i am going to go with some of this 3/16" thick buna gasket i found at work in the scrap pile...going to try and cut it nice with a hot knive and if it looks bad just order up 8 watercut pieces... most likely going to just rtv them to the head...

I would epoxy the floor of the runner about an inch deep into the intake and sand it to where it makes a smooth gradual curve into the head port.
I dont look at it as making the port smaller because the intake port on the head is already doing that for you.
Maybe you will not gain but 5hp but if you dont you will never be able to get out of your head "what if"

also the gaskets seem to put the ports alot more in line...just need to cut them out tomorrow/this weekend...

If everyone took their intake manifold top off AND their heads are milled they will not line up correctly, it will always be off.
But this is strange because it is off at the bottom... Call FAST.

How do you build an intake to fit every set of heads out there? Some heads are unmilled, milled .030-.040. Not every head has the exact same dimensions as stock, for obvious port flow reasons. Looks like the TFS heads have a little bit of a raiser runner intake. I port matched my fast intake to my 243 heads I had milled .020. They lined up great top and bottom, but side to side some of the ports were up to .060" off.
No one said everything is quick and easy in life. I have over 15 hours alone in porting my fast intake. Make sure you seal your intake back up with a little silicone as the fast intakes have been none to leak internally, causing hp losses. I would smoke test the intake after you are done, these damn plastic things are a pain to seal up.
You should seperate the middle and the bottom piece to radius the entrance to the runners. That and remove the big bulge on the side of the entrance.
