I hear about how some guys can R&R heads or entire engines in record time, but I have had mixed luck doing so. Maybe some of it is because of the car.....
I have to say that having 2" headers makes this sort of job a real pisser. To get the heads off, the headers have to come out. To get them out, the center link gets unbolted, the trans linkage too. This of course requires lifting the car to what feels like an almost unsafe height so the angle is right for installing or removing these headers. I'd never switch to manifolds, but I can see why many people stick with them.
Going back together, most of the header bolts are easily reached except near #1 and #2 tubes. I sometimes forget to tighten down the starter leads before bolting the starter in place. They are almost impossible to reach afterwards with the headers in place.
I'm almost there, just a few things on the top side to finish. I have both the Fel Pro intake paper gaskets and the thicker Mr Gasket ones. I figure that the thicker head gaskets may require thicker intake gaskets to manitain proper intake port alignment.
