I used a long piece of heatshrink when doing this. However, I found the LS1HowTo article to be very informative on an easier way of doing it. If you look at the dot on the crank timing gear you can tell which pistons are at TDC. Check out the article and look under the "Top Dead Center Method" section under option B.
Of course, this is assuming that you also have the front cover off. If not, disregard this post.

electrical cord, a straw, or anything thats not going to break off. check out the LS1howto guide posted above. that will give you the cam and crank gear locations, and also tell you what pistons are at TDC.
when i did my valve springs, the TDC method worked great for all cylinders but #8 all the way in the back on the passenger side. the valve will fall a VERY little bit without compressed air, but the little bit makes a huge difference.
Good luck
