Some of us have been running headers for a long time and have good experiences with them. I've been running Hedman's for 8 years w/ minimum issues. I also coated mine with the POR-15 gray manifold paint 4 years ago and it hasn't burned off. As far as heat soak in the stock starter, it's a minor annoyance. The oil filter issue everyone is talking about, I use the NAPA 21042 smaller filter and have no clearance issues.
