Okay, question. Took head to shop and had to have all valves adjusted. When I picked it up everything was together and he explained to me how to install new cam seals since I didn't give him any (wasn't expecting valve job). He told me to simply push on new seals. In the TSRM it says install new seals while cams are out, temp install bearing caps with seal packing under #1 cap (Whats the name of the seal packing y'all use and where to buy?), tap in cam seal, then torque down all bearing cap bolts. Should I just push on new cam seals like machinist said or do what TSRM says and take apart cams to install new seals?

It was almost $500 job so I don't want to take apart cams and screw something up if I don't have to. (first timer so correct me If I'm wrong and taking out cams won't mess with valve adjustment)

Thanks!
