if your aluminum+phenolic+gaskets is the same height as the stock injectir blocks i will take a set.
That orange you see that looks like a gasket is the surface of the phenolic insulator.

Yes, the height of our assembled stack [insulator+block] is the same as the factory plastic block, and we use factory gaskets top and bottom.

I apologize, but we just ran out. Fortunately more are already in process, ready soon:

Regarding the factory manifold -- it is magnesium alloy and surprisingly flexible.

If you think yours is not true, that the 6 surfaces aren't level, verify this on a flat surface -- machinist's table, a granite counter top, etc. Shine a light behind each intake flange, and you'll see if it's flat to the surface or not.

If not, you can stick down some 320-grit sandpaper, lightly oil it, and deck the taller runners' surfaces by rubbing the manifold around on the sandpaper in a figure-eight pattern. This ensures you don't take of material at an angle, more on one side than the other.

Another test is to smoke test the assembled engine from the throttle body to the exhaust. Plug off the exhaust tip(s), and use the kit's adapters to connect to the throttle body, fill it with smoke and pressurize it. The newer smoke testers can usually do 12-15psi -- ideal for finding common boost leaks on Turbo vehicles.

Finally, on performance builds, we almost always wet the gaskets with a little Loctite 574 anaerobic sealant. Then minor pitting of the manifold is no longer an issue.

just ordered your blocks. rough time frame to get them?

how does it seal without a gasket?

no, it is not flat. and by that i mean around the actual port on just a few ports, there are some low spots. i put a straight edge across the edge of some of the ports, turned out the lights and i can see light under the ruler. it is very very small, but i can see a gap.
i put a little JB weld on a few spots. gonna sand them first, then do as you said. i have a large piece of thick glass. i did this last time but maybe not enough or they have distorted some more. the blocks i just took off look like crap, and they have less than 5k miles on them.
what a waste of $$.

chris, maybe make mine 1mm taller and/or send me the gaskets to go between the insulator and the blocks. yes, i am being paranoid. i have been trying to find this issue for a year and have had the intake off now 3 times to fix this. i need to be 100% certain there are no air leaks if it does not run right after this.

well things are looking better.
got the intake flanges all straight. thanks chris. i did that before but used water not oil and i did not do sand it nearly as much as i did this time. there is still just some small amounts of pitting and small amounts of JB wled left, so i know i have it very close.

fisxed another issue.
my idle would not always come back to the same place when i let off the gas. sometimes 1000, maybe 850, maybe 900. so i removed the idle screw and it was very dirty but the proble was the throttle plate could not close completely. the throttle switch adjustmnet was keeping from closing all the way. so i just pulled it off, dont need it. throttle body is all cleaned up and working as it should, it sure feels good when you actually find somehting not right and get it fixed.
