do a search for engine deck cleaning.make sure to remove any fluid that goes in the bolt holes in the block.a shopvac is nice to have to remove any junk.if using stock gm head bolts you will need a torque degree wrench from snap-on.

Don't need a torque degree wrech, use the old trick of drawing a vertical line on the bolt and using that to reference you amount of twist on the last torque step....saves time and money
