changing them isnt as bad as everyone says it is. I've done two sets recently. just check and recheck everything you do under the valve covers, because its a long way in there to fix a screw up. be sure to get you a vaccum gun to vac test the return lines before you close it all up. it's cheap insurance.
smoking duramax ?
