There's a reason it blew--you need to figure out what that reason is before putting it back together so it doesn't do it again.

Check the block deck surface for flatness as well as the head surface. Do NOT use a Roloc wheel to clean off old gasket residue, use a wire brush and a gasket scraper.

If the gasket blew between cylinders, look for damage between the bores on the block and the chambers on the head--the hot gasses can literally torch away material leaving a trough behind.

Replace the head bolts with quality replacements.

Measure the old head gasket thickness or look for a part number so you can replace it with the same part--or at least one with the same thickness. Composite gaskets go on dry. Steel shims go on after coating both sides with Copper Coat and letting it tack up a bit.

While it's apart, run a thread chaser through the head bolt holes, and the intake & exhaust manifold bolt holes to make reassembly easier. If you have to remove the rocker studs, don't forget to coat the threads with sealer before reinstalling.
