I had the manifold off in about 1 1/4 hours and put it on in about 1 1/2 hours, cleanup & gasket prepwork took the longest. I spent a half hour with my plenum plate on the wire wheel cleaning the old gasket off and another 45 minutes on the intake & heads sanding the old gasket meterial off by hand since I couldn't find my sander and I also changed out for the 180 thermostat. Then I took my time with putting the copper permatex on the coolent ports of the intake as well as the plenum plate and to complete the job I also changed plugs,cap,rotor & wires. Probably 3 1/2 to 4 hours the whole thing took me to complete the whole intake job, finding & getting tools set up & ready was the time consuming thing. The average person shouldn't expect results like mine, this is my 5th intake job on a Magnum/Ram motor and first time on my own Ram.
I did use my dads battery impact to take certain things off like the ac pump so I could fold it over to the fender so I didn't have to worry about losing freon. The biggest thing is having your tools organised and sockets on rails! do this before the job!.
