I am not sure what shroud I have. I believe it has the veins. I don't have the flap system in place as we don't drive the car in cold weather. We don't like to drive it when outside temp is below 65% degrees.
Also, since the CHT are within reasons, don't think there is an issue with the fan flowing air to CHs. Yesterday I ordered a welded fan and the T4 oil cooler. I will need to do some fab work on the shroud.
My son and I are pretty good at getting the engine out. We can have it out in 45 mins. Putting it back in is the PITA.
