Hey guys thanks for all the info, I'm no mech. by any means. I definitely know how a header works though. The issue is even the stock manifold off of the ls-1 won't fit my application. so i opted for the shorty block huggers. I'm mainly snaking my steering now so I needed the headers in place. I'm going to leave all the performance up to an engine shop. My project is for more reliability than get up. With that being said I'm sure we will add a few power adders to make her not be a slug !!
