Default Stock LT1 head chamber CC

What's the chamber CC of a stock LT1 head? I'm sure this is out there somewhere but I can't find the search button since the redid the page. A little hint on that wouldn't hurt either. Thanks.

That seems really small! I'm looking for new pistons to drop my compression ratio and I don't think I'll be able to drop it as far as I wanted. Oh well, time to do some chamber work and get the -24cc dish pistons.

Depends on what youre trying to do, but you arent going to get more than 56cc or so out of the LT1 without hurting your flow numbers or killing the quench pad.. which would be bad bad bad :)
