I don't really have any way to heat them up that hot. no torch.
Plus the exhaust is still hanging off them. That would suck up a lot of the heat.

I had thought about unbolting the motor mount, but I remember how much of a pain it was getting them in, I am afraid to do that.

I just wish I could remember if we stabbed the motor in with the manfolds on or if I put them on after. if I did it after then they had to be out and I coated them with anti-seeze(sp).
