Chewbaca is an unknown quantity at this point
Default Top end reassembly...what goes where!?!?!

So I am installing new top end gaskets to my 72 XLCH. Problem is when I took everything apart, i didn't label what was front or back.

The heads are painted and I can't identify which is front or rear, although I think the exhaust and intake ports can help me figure out which is which. The intake port has a thinner lip as opposed to exhaust port that has the wider lip for the pipes to slide over. Correct?

The rocker boxes however, have a number 1 and 2 stamped on them. Can someone explain which is front and which is rear? I don't want to put them in backwards!

Thanks!

The intake valves are the largest valves. When you install the heads these should face each other.

Look at the oil feed lines to determine F & R rocker box.

Make sure pistons have valve relief on the intake side.

Not only do the intake ports have the thinner lip you mentioned, but before you crank the proper 65ftlbs of torque (in three increasing increments) make sure your intake manifold is properly lined up - the intake doesn’t actually touch the heads in the correct position, it will have an equal gap all the way around between both ports at the same time; it’s the intake o-ring’s job to fill in the gaps - then torque the head bolts. And make sure the head gaskets match the two oil drain holes in each cylinder!

Also, if your motor is in the frame, I think you want to have your rear rocker box in place, with gaskets and bolts, before you place the rear head on the cylinder. It doesn’t have to be tight but at least in position.

Once the head is on, there’s no room to get the rocker box in there between the frame tube and the valve springs.

+1. Good point! In fact, leaving the rocker box loose helps you to get down onto the head bolts.
