The trick is to get the quench height correct, not so much the zero deck part. You can have the pistons 0.015 down and use a 0.026 gasket or have them 0.005 down and use a .036 gasket. Ok I understand it now better. So I'm running Aluminum heads and you stated before you like the pistons .005 in the hole with a 0.036 gasket? So does anybody really what the best quench height is or is it just a guessing game? In those builds where they really were getting good hp and torque numbers they never really said what gaskets and so forth but it was just a zero deck build. I want to run an engle k58/k60-110lsa hydraulic cam but I'm still lost with carb set up. I think those people used a 950 hp holley but do I really need one that big? Whatever I use I want to run an electric choke. A rebuilt 440 with 10:1 compression and Edelbrock heads should make about 500 or 525 hp. The carb needs to have 1.4 cfm per hp so that works out to a 750 carb. You do not need a 950.

The thin OE type metal gaskets were made for iron heads. Some folks have had good luck using them on Al heads... but many, me included, prefer thicker composition style or Cometic MLS.
A standard Felpro blue composition gasket (.038-.040") seems to work well with BB and aluminum heads on a mild build. Ok thanks. I think I'll get it square decked and just do from there.
