Impala head Gaskets? Yeah or Neah?
What year Impala SS head gaskets does anyone recommend?
How much of an improvement will they yield to a LT1 with a hot cam? Compression and HP?
Does anyone have a GM part number?

They'll bump compression around a half point, so you'll go from roughly 10.5 to roughly 11.0.
The bump in CR will be worth 5 - 7 at the rear wheels with proper tuning.

I've used them both times I've had my heads off. With my aftermarket pistons they give me about 11.3:1 CR. It's like this.... why not?

I don't know, I am new to this and I ask a lot of stupid questions.

I've been fooling with cars my whole life, and that's a long time but nary a day goes by that I don't learn something new here. I don't really know why the Impala's LT1 used thinner gaskets (or the Y & F bodies a thicker one) but since most of the heat is already in the head, don't worry. The LTx engines' whole design premise is to deal with that very effectively.
