Im looking at the same build with a .030 block. I need to rebuild my 340 that's got a cracked x head and damaged trw L2322 .030 pistons no longer avail. If I go the eddy heads, I lose my 12.6:1 compression because I can't find replacement trw's and cant find anything but lower compression flat tops to match the eddys. What are Campbell able to offer?
Thanks
