Changed intake gasket, now it won't start

Are you kidding me take it to someone else and do it! With all this practice you should be able to do it with your hands tied behind your back and your eyes closed! I mean you got it easy. When this sort of thing happens to me it's the pan gasket underneath the car I have to loosen the motor mount jack up the motor and then oh my goodness the nightmare of it all! We're talking an intake manifold you don't even have to grovel around on the ground. When I put my new Stroker motor in milodon gave me a pan that had a hole and one of the welds! And then there was the time I had to take the pan off because the motor ate the dipstick! what a nightmare please please the next time let it be me just having to take the intake manifold off!
