AFR 205 heads & lifters install Questions ?
I'm looking at getting a set of these soon and have some qustions.
1. Will my Comp 921 springs fit right on them without the need of any other parts ?
2. What gaskets should I use ?
3. Are GM head bolts stretch style and need to be replaced ?
4. I'm changing lifters as well becuase I have a bad one (I think), should I go back stock or Comp R lifters ?
Thanks for any help.

What pushrod length did you use ?
Are your heads milled or standard ?

Just do Comp 850 lifters. They are OEM replacements and don't need you to screw with anything. Ususally, they are cheaper than stock and far better.
If you have the money though, the Morels would be a good choice, because they do not need adjustable rockers.
Comp R, as I've heard from both Comp and TR, need adjustable rockers for proper operation.

As for the chain I think the LS2 chain is the way to go, cheap and very strong for the money.
I would suggest some dual springs such as the 921's or whatever brand you like.

Unless your going turbo, big cubes or supercharging he said it was bigtime overkill to use the 'R' lifters.
I like the fact that it would be overkill but I don't like the fact that I would need different rockers to make them work as they were designed and using them any other way is not getting the benifits the lifters offer.
I was told by a shop that I could use the 'R' without adjustable rockers and just make sure the length was right but Comp said its not only a bad idea but its a terrible idea.
They also said the OEM style lifters are rated higher than factory and would do just about anything I wanted them to do short of running 7500 RPM all day.
