Hi, I will be putting the head back on my 91 nissan king cab as soon as the weather here dries up, and am wondering if a gasket dressing should be sprayed on the gasket before it is put on. I have never done a head gasket before.
I have some gasket spray which would certainly hold the gasket in place and is good to 450 degrees F.

All the cars I've done have pins on the block that hold the gasket in place. You don't want to add anything because that might get in the way of a proper seal.

Make sure both the block and head are flat with no gap if you put a straight edge across it. Make certain you use new head bolts and go through the proper torquing order according to the manufacturer.

The head should be pressure tested if there was an engine failure.

Thanks for your kind and accurate replies, guys. I didn't use the gasket dressing but managed to put the timing chain in the wrong place on the camshaft sprocket. Hope I didn't screw up any valves cranking on it. Will take 'er apart and try again.

Hope you didn't bend any valves.

Always crank it one or more rotations on the crankshaft by hand and then check the timing marks again after a few revolutions.

If the marks moved it means you had too many links on one side of the sprocket and/or the tension is not correct.

Same goes for a timing belt.
