Review on Hedman 69840 Chev Gmc 88 95 by Wayne Seba

These headers were difficult to install due to lack of space as probably all headers are. Everything I needed for my setup was included. The quality of the headers looks good and they have not rusted yet. I bought them from Revain because after delivery they were cheaper than elsewhere, although the purchase price was a little higher. They sound good too. How much they affect performance I can't say as I installed a new camshaft with roller bearings, a whole new exhaust and several intake modifications at the same time. All of this combined was a noticeable improvement, but I don't know how much power I got from titles alone and how much from other mods.
