Junkyard 5.9L Magnum + Edelbrock LA heads build

Now a question, what head gaskets should I use? My machinist recommended Cometics but I've read the block deck needs a special finish for them to seal right. Is there a better option for head gaskets that will work with aluminum heads on an iron block that are available in .030" thickness or less? Even with .027" Cometics my SCR will barely hit 9.5:1. I would like better head gaskets because I do intend to convert to EFI and add a Procharger at some point (and yes I know all the risks of that, please don't lecture me about boost and blowing stuff up I'm getting tired of hearing it).
