I emailed a guy at carparts.com about soem headers that cost 170 dollars and he said he review and researched it for a couple of days and said that they should work. I think i may try it soon after i get my suspension worked out.
ya, i have the headers on my truck and the seem to leak a little. i must of spoke to the same guy as you, because i have had problems with the ports lining up correctly. They may be a defective header because they are made in mexico. I am getting new ones in the mail so ill tell you if they work 100%. right now they only work 90% because i recut the gasket so they won't leak. resistance between the head and the header in the 1st and 2nd port/piston, is the problem.
