I see everyone saying that it does not fit. I have it installed on my '02 CG with a stroker 6 cyl. It's a tight fit, but it does fits! No leaks!
I did use a Fel-Pro gasket instead of the one provided, simply because I already had it. Metal seems to be good quality for the price. It's only welded on the inside of the tubes at the head mating side, the outside is only tacked in place. That's the only thing I'm not keen about, for the price, it's not unexpected plus it's a simple fix. O2 sensors fits well, nice tight seal. The head mating surface was strait, no issues there. Just little larger surface than stock manifold's surface. I suspect this is where people are having fitment issues.
For the price compared to big name brands, I'm overly impressed! Time will tell on durability, though I don't expect issues.
