what gaskets to use with aluminum heads?

We have used the 440 source head gaskets on two of our engines one with edebrocks and another set on our stage6 headed motor. We blew the set on the stage6 headed motor but really cant blame anything but the combo, stock shortblock pistons way in the hole the heads were milled alot when we got them so we ended up with around 10.5-1 the wrong way to achieve it and running too much timing so I'm sure you can figure out what happened, was running 11.50s like that though(in the duster) for a while lol, but it was a nothing shortblock and we knew it probably would do what it did and it did.the edelbrock headed motor is still running strong(til I took it out to adress some other driveline related issues with the 440 source headgaskets. I just took the 383 out of our duster that replace the mentioned stage6 headed motor and put in an iron headed 440 with the steel shim headgaskets and it seems good so far(just fired it up last night) didnt put anything on them. We have used copper gaskets b4 a long time ago and I think we sprayed them with something(dont remember for sure though been like 10-12 yrs since) We have used the felpros with 0 issues as well with aluminum heads.
Good luck,
