Ok so where do I get these ball socket bolts and What collector gasket do you guys reccomend ? Because thats all that it leaking on my the manifolds no longer leak since i changed to stage 8 bolts and copper gaskets.

I know this thread is a few months old but I wanna add my $0.02
With basic bolt ons and an OEM HCI, you can actually HURT performance by adding big primary LT headers. How? Inhale thru a straw and exhale thru a paper towel tube... Notice anything?? Right, zero back pressure which leads to poor exhaust scavenging which leads to a loss of torque that no truck should be without.. Yes!! LT headers generally make more power than shorties and especially cast iron manifolds. However, LT headers make more power in the higher rpm range which, unless you drive in the 3k to 5k (or whatever your redline is) constantly you really don't see the power you paid for. You actualy feel the drop in low end torque that leads to crappy fuel mileage. Now, for those with higher flowing, purpose built engines (or LSx swaps) will greatly benefit from LT headers due to the added airflow through the engine. (remember the straw/paper towel tube analogy I mentioned? Reverse it and it applies to a free-flow topend and a restrictive exhaust)
Also, my headers have the old style flanges on the bottom, that take the triangle type gasket, i just buy the cheapo Mr.Gasket gaskets and put orange silicone on them, no leaks yet.
ugh. U DONT want backpressure, you want velocity.
