It's pretty easy to R&R the intake. If doing it alone, some people have used clothespins to hold some of those bolts up out of the way, so you can lift and slide the intake up off the engine without snagging anything. Another "while youre in there", is why not replace the oil pressure sender, if you haven't already done so........
