The 2nd Gen swap s464 was the best mod I ever did to my truck.

I went with Smedings kit and hhadabout a thousand miles on it with zero leaks or issues.

The fitment can be tricky in some areas, but I got it done.

I would also get Ray's tuning, by the way, and like stated before, head studs.

The 2nd Gen setup is supposedly easier on the head gasket versus the VGT, but I won't turn mine up unless I have head studs in.

The ARP 625s are also on a national backorder.
