For everyone elses info... If your going to block off the coolant passages to the tb, it helps to open up the coolant passage in the LIM located under the EGR/LIM. You can do this by taking off the plate and drilling or notching out another 1/4" to the passageway. This is to make up for the coolant that was supposed to be going to the rear head but is now blocked at the tb/lim.
