I have everything on the way via UPS for my heads and cam swap except for headgaskets. Stock LT1 headgaskets will be just fine, but I have a question about ordering them. I looked up the part number on www.gmpartsdirect.com and got a price, but I don't know if it's for one gasket or two. The part number is 10168457. Can anyone help me out here??

They are priced and sold individually.

Why aren't you going with the Impala SS head gaskets? worth about half a point in compression ratio.

That's what I'm using on my summer buildup.

 

I would like to do the impala gaskets, but I'm getting the heads milled 20 thousandths, and was worried about issues with the intake manifold sealing. Do you have the impala SS part ##? What do you think, should I be worried about it?

Hmmm..well, that is a good point, and between milling and the thinner gasket you'd be looking at more than 11:1 comp. As to the intake manifold gasket sealing issues, that's one of those situations where it seems like for one guy it works fine but the next has constant troubles with it.

I have the Impy gasket PN# but its at home, I'll have to e-mail it to you.

I didn't get my new heads milled, that's why I'm doing the Impy gaskets, otherwise it would probably be more compression than I care to run on pump gas/daily driver.
