So I've got the SR apart and decided to change the manifold arrangement. I pillaged this manifold from a car I parted out a few years back. As for function, it works fine, but being the anal retentive person I am, I just can't keep it on my motor. The real issues are the following...
1) the casting is pretty rough on the inside and out. It's not the worst of the aftermarket Freddy manifolds, but its definitely not one of the better ones.
2) the runner surface is not perfectly flat but with gasket tack and a thermal intake spacer, I had no problem getting it sealed.
3) the counter bore for the #4 injector grommet is a little light on material. I assume that the casting just didn't have the material needed to go the depth they machined. Luckily a decent injector grommet covers/seals it up. I was very religious about pressure testing my system and never had any leaks.
All in all the rest is okay. Some of the threads have seen better days but they still work and torque down well. I realize this part isn't perfect and I want you to be aware of that when you purchase it. If you need further pictures, let me know.
Price: $50 shipped

Here is a picture of it on my engine. I made over 400hp @ 20psi with it.
