I have a couple issues:

1. The gasket material off the old heads is on there pretty thick. I wanted to use a gasket remover (metal brush thingy for drills) to get rid of it. For one, I hope that brush isn't to rough, that it will damage the mating surface. Another problem is my engine valley is exposed, and I don't want that crap getting down there. Especially since my car has a HARD 97K, and there isn't ANY ridge on the cylinder walls, hell, it looks like it has just broken in good. Damn, I love the LS1. What is the best way to remove the head gasket material without making a mess?

2. What is the torque down procedure for LS6 heads? I need to know the torque specifications and order.

3. Why in the name of GOD did GM bolt grounds to the back of these heads? That is gonna be a real mothaf*cka to bolt that crap back on there. I would almost rather bolt it to a GOOD ground, such as the frame. It would ease head exchanges, plus I wouldn't think Aluminum would be the world's best ground material, anyway. I don't know, now that I think about it, that will be time-consuming the do it that way to. :thinkin:

4. While I got the heads off, do you guys think it would be wise to change the lifters too?

1. Whatever you use, be careful. The aluminum is very soft. You don't want to gouge it.

2. http://www.ls1howto.com/index.php?article=3

3. Don't forget the block needs to be grounded for spark.

4. Might as well get some Comp OEM lifters. Change out the lifter trays also.

Thanks Ed. Very helpful. I would have to wait to get those lifters, I think. That would delay my whole project at least 3 or 4 days. Hmmm...the stock stuff should be fine, right? I can inspect those lifters at least to make sure. What should I look for, like shakey roller tips? It wasn't ticking at all before the de-stall.

use laquer thinner and mild steel wool on the gasket left overs or softly hit it with a conditioner pad,

Too late, I ended up using a wire drill brush and a sanding block for the stuff I couldn't get to. I used a plastic windshield de-icer scraper to get the big stuff off. Cleaning out the bolt-holes turned out to be a real time-consuming mofacka.

Next time I will try the thinner and wool trick. That is a good idea. Maybe you should email JMX at the HowtoLS1 website and see if he will include that in the install procedure. It sure would be helpful.
