Bring your crank dot to as high at TDC as possible, and line your cam gear up. Done. Don't worry about anything else. As long as your dots are lined up, you will not line anything up 180 off.

Even if you were one tooth off it wouldn't hurt anything, just might move your powerband around a tad.

No prob. Don't forget to use loctite, TQ your cam retainer & sprocket properly, make sure to use a new crank bolt. Also before TQ'ing your rockers wiggle your pushrods pushing them down some to make sure they're seated on the lifter properly and that the lifters drop back down on the cam. This will ensure a more accurate TQ reading.

Good luck

Make sure the lower gear goes on right as well.

Thanks for the advice, I did use it. Most is covered in the ls1howto write-up except they seem to lack a bit of info on properly torquing the rockers. Other than that it has been a great guide. I have done many engine rebuilds before, w/o a guide, just doing it off the top of my head and I'd get everything back together and go "Oh ****, I don't remember torquing the cam retainer plate down!" lol. One other think I noticed on the ls1howto guide is that it says 1-2 hrs for disassembly and 1-2 to reassemble. Uh, no, I know my way around an engine and am pretty diligent in getting things done. I have had no major hang-ups on this cam swap, I haven't rushed it but I also haven't gone really slow. I'll have about 12 hrs in it total by the time I am done. It would probably be about 8 hrs if the engine wasn't underneath the dash. The springs alone took me about 3 hrs and thats wiith Tim's Tool. Then having to change the timing chain was a bit tedious because of having to lower the oil pan. Its all good tho, I just have to bolt the water pump back on along with the radiator and fans and its go time!
