manifolds vs. shorties
i have ps shorties on my truck right now and im tired of the leaking on the passenger side. im sure this is were some of my mpg went. i am going to gasket match my manifolds and put them back on. My question is do you think i will lose any power doing this? truck is in sig.

I think that if you have 1.625" or larger shorties with a decent collector they will make a little more power than stock manifolds. So you may loose a little going back to the stock manifold.

Where are they leaking from, where the header bolts to the head or to the y-pipe? If you're on a budget and can't afford new LT's, and it's where it bolts to the head, get some factory exhaust manifold gaskets and give that a shot. If they still leak, some high temp RTV should fix you up (the copper stuff that's orange). If it's leaking where the header bolts to the y-pipe, you could also try some hi-temp RTV and see if it works. When I installed my Gibson shorties, I used the copper RTV on the head to header gaskets and where the headers bolted to the y-pipe and had 5 years of service with no problems. They were still sealed perfectly when I removed them to upgrade to StainlessWorks LT's and catted y-pipe.
