I like the fact that I found this part because its exactly the same as the original GM vortec exhaust manifold gasket.
I rebuilt my 98 Silverado 5.7L vortec motor a couple of weeks ago and I knew I would have interference problems with
my oil dipstick and sparkplug shields if I used anything else. These are made out of stainless steel and fit like the originals. I did opt to go with Dart heads on my rebuild. Couldn't be happier with that combo. Good for another 250,000 miles.
