Are you planning on changing the valve springs at the same time, or just a cam swap?

You'll need to remove the rockers before pulling the cam anyway, and with the timing cover pulled, it will be easy to use the TDC method for the valve spring change. The dowels are used to keep the lifters up when swapping the cam.

Mark the gears?? The cam gear and crank gear have timing marks on them already. I agree, it sounds like you would be well served with a service manual sir.
Good luck with your project.

I'd suggest NOT doing the head on cam change. Sure, it can be done, in fact I've personally have, but when, it was to evaluate a number of different cams with the intent of the engine being tore down at the end of testing. However, for a engine that I plan to run a number of miles pulling the heads just make good sense.
Your car, do as you wish.
- If one of your lifter rollers is marginally damage and you place it on your new cam, guess what happens to your new cam.
- Pulling the heads allows you to clean off excessive carbon from the combustion chamber and piston.
- Easy inspection of pistons tops.
- Check piston to valve clearance.
- Check bore condition.
- Clean intake assemble.

I second www.ls1howto.com also... and don't use the stock bolt method to install the pulley definitely chance of damaging the snout, a longer bolt is needed for that.
wether or not you pull your heads is your choice, i did heads at the same time but have done trans am 's without pulling the heads it's difficult to get to all of the bolts, I if there is a problem with the lifter you should see it on the cam you took out, then you need to pull the heads.
dowel? wooden? I wouldn't, a couple of pieces of brake line work just as well, or brass brazing rod, lot cheaper than the $150 tools they try to sell you.

).You need to follow the service manual. I made a tool to do the same thing that the service manual uses from threaded rod, some nuts and washers. Don't use a bolt to pull it on, even a longer one. The service manual ensures full thread engagement before any loading from pressing on the "pulley", which is an interference fit that requires considerable force to get on. Here is the tool I made.
Here is the tool in use.
Here are some relevant pages from the service manual.

This is a Ridgid pipe strap wrench. Bill Curlee posted a pic of this on his motor and I did the same to hold the motor while your trying to get that 250 lbs of torque.
What size is that pipe strap wrench? You were able to tighten the bolt by yourself?
