340 High Compression Pistons

...watching. I posted about my hydraulic lock issue that has turned into a broken 340x head issue. It has the trw 12.6:1 pistons also. Not a stroker and dyno'd 450+. When I pull the heads this weekend, I'll probably find myself in the same boat needing a new 340x head and pistons. If I can't find replacements for both I'll be chasing a new high compression piston / high flowing head combo and needing the same help finding something fairly straight forward to use. The indys and eddys were my first thoughts too because the magnums won't fit my intake and TTI headers.
