When you get around to putting the manifolds back on, take a good look at the heat riser on the passenger side manifold. They have a tendancy to stick closed, causing overheating problems. They need to be constantly freed up with a high temperature lube like Jigaloo Extreme Graphite (in a green spray bomb). Some guys even gut the heat riser, taking out the round butterfly valve, but leaving the control rod in place with the spring. It looks stock at a car show, but won't ever cause any problems.
