    I have the heads off of my 351C to prepare to add my new Aussie heads to the setup. The bottom end is still together and it is what it is so I need to try and work with what is there to get the proper deck clearance for the quench. My pistons are .019 - .020 down in the hole, so I am looking for a head gasket that would allow me to reach the desired deck clearance for the quench to be effective.
    Most composite gaskets seem to be in the .038 to .041 area. What are my choices beyond this? Should I go copper or MLS ? Or will I be OK with a .038 gasket with a total clearance around .058 ? .040 to .045 total deck clearance seems to be the sweet spot to shoot for, correct?
    The heads chambers are around 65 to 68 cc (will be finalized as I finish the heads and have them milled) and I would like to try and keep my compression around 10.5:1. If it ends up a little less, not a big deal, I can adjust components accordingly (mainly cam).
    Any suggestions or advice for me here?
