next week i want to get my intake-manifold off to polish the intake cambers and grind the welding-craters off and adjust these to the intakes in the head, by that way i am thinking its a good situation to change the gasket with a plastic one. i could get them from ebay, they have them with the egr-holes and without to block off the exhaust gas recirculation

now my question: is it a good idea to block the egr off or will i have to come in trouble with that modification? and is it worth in relation of taking the heat from the manifold off or does that nothing in celsius or fahrenheit?

There is some advantage to blocking it off but i forget specifically what it is and if anything else is involved. I saw a thread on exactly this same thing on m.net a few weeks ago(minus the teflon). I would search there.

Teflon is the incorrect material for an insulator gasket.

The optimum material is phenolic (which is more expensive), as used by Outlaw Engineering:

it'll make you NOx go up. <--- currently unsmogged cuz of high NOx

any idea where I can get phenolic sheets?
