Just take your time look at my avatar took me 1 hour with the dremel and 4 hours of sanding with one sheet of 120 grit turned into 1000 grit and some burns and blisters on my thumb and index.
Good luck.

And putting the tubes in the holes does nothing for hp.

I do them. I have one that is almost done minus the cleaning of the exterior that has the bump stop mod, half-shaft, almost mirror finish, knife bladed the front end of the blade, and has the drill mod for a bigger cam. I can epoxy the hole for the drill mod if you would like or from what I am told you can just let your car run until it relearns its idle. I think this one could go for $100 plus your core.

ya theres an awesome write up on the bump stop mod that a guy did on here that wasn't stickied and should have been bc it had nice pics and step by step instructions. I followed that one and had no problems really didnt feel any gain from it though.
