Is it hard to install an intake manifold gaske in a 2001 chevy venture? A dealership quoted me $1600

1600 WOW way to much DO NOT DO IT!!!!!!!!! Its not that hard at all to do I would just recommend taking your time and buying a book on it. And the one common problem is that you need to take yout the push rods. and tHEY ARE DIFFERENT LENGTHS FOR EXHAUST AND INTAKE. Just make sure you dont mess that one up. I think i did that same job for 200 buck labor a few months ago.
