plugs and cam

When you do a cam swap do you have to remove the spark plugs?

it's not required but since you're going to be taking everything apart you might as well. I think a lot of people go with NGK TR55's, and NGK TR6's if you go nitrous.

You do if you replace the valve springs. you will need to pressurize the cylinder when you remove the springs to prevent the valve from falling

I had another question.

If I change the springs with the cam still in the car will still need to pressurize the cylinder?

Yes, the valves will still fall even if the cam is still in there. you still need to pressurize the cylinder to get the spring out.

Agree. the cam only opens the valves. The springs are what keeps the valve up. once you get the can torn down you will see exactly how everything works. go to www.ls1howto.com and read up a little on the cam swap. If you do not feel 100% confident on doing it yourself then either have someone experienced with this help out or a good shop. Its too much to risk if there is something not done right.
