does anybody know of any good how to articles about installing cams. I'm installing some cams in my car, but i lost my haynes manual. so i need some guidence because i don't want to f this up. I've done it before i just want to be completely sure about every move. i've already taken everything off, but i didn't put the crank in the safe mode or tdc before i did this. how screwed am i?? i should be fine because the springs are holding the valves closed so i should be able to turn the crank to tdc or 1030 now for timing sake correct???
