I used the OEM intake gasket to port match the LIM to UIM, and the gizzmo phenolic gasket to port match the LIM. It wasn't a lot of material but it sure did take awhile with the dremel.
Now that its done, I'm not sure if this was a good idea or not, as a local rotary expert told me that while it will help top end power by a few hp, it may create excessive intake reversion and low speed cruise backfiring/sputtering. Anybody else have any experience with this? I'm hoping the effect is minimal on my mostly stock ports as I anticipate a bit of a driveability loss already by replacing the stock throttle body and loosing the way it opened up the primary butterfly first.
