Yeah, all that hot air is robbing power. Have you had a chance to log IAT temps yet? Header wrap works serious wonders and it's not that expensive. Find some header wrap on Jegs or summit, and get the can of heat barrier spray with it. Both the insulating spray + wrap will cut down temps on the header so much, you'll be able to touch it after a few hard pulls without needing a skin-graft.
The problem with this is, this allows moisture to be trapped, and basically raises the risk big time of your tubular manifold cracking early. Which is why I say go ahead and save up now. By the time it cracks/you get the FP manifold, Shane will HOPEFULLY be making his FP manifold heatshields, so you'll be golden by then.
