Installing the head while engine is in the frame

I remember reading some handy tips, like the rubber bands holding up the push rods, but couldn’t find much by searching. I assume it’s going to be just as bad, or worse, than removing it.

I am at same step as you! I took my head off a couple of months ago and it took its of fussing with the pushrods. I think putting back will be easier because I will be able to know beforehand where in the head to push each rod up to. There are suggestions of rubber bands which is a good idea

When you put the head on make sure the push rods are inserted into the head as far as possible. Use the rubber bands to hold the rockers down into the push rod cups once you have rocker inserted into the cup. A hook shaped pick works well to pull the push rod into position.

Have heard, never tried, removing front iso bolt to let engine pivot downard gives you a touch more clearance for head fitment. I managed head r&r before i heard of that trick. Used the rubber bands but a bit fall in a tunnel when cutting them off later...got it out with a vacuum cleaner and small pipe.
Used a long thing screw driver and flash light to get rods correctly seated in rockers.

From the manual. I found one YouTube video that helped with removal, but none for installation.

As already said, get the push rods touching the roof of the head and retain with elastic bands.
Don't seat them onto the rockers and it's fairly straightforward
