Lubricate the new head gasket with 2 cycle oil and bolt the cylinder head back onto the motor block. The holes on the cylinder head are not symmetrical so that the head will not go back on the wrong way. You may need to rotate the head 180 degrees if the bolts do not seem to line up. Be sure not to over tighten the bolts. Everyone seems to think that head bolts need to be really tight. This will only warp the head. Again, only tighten a quarter turn past snug. When you tighten these bolts, you need to snug down the bolts opposite each other for evenness until you have them all snug and then go back around until you have them all tightened a quarter turn past snug. This way the head will be evenly attached to the block. This tool will download and update the correct.
