Working on the 426 Wedge for my 69 RR. I picked these new pistons up at the Portland swap meet earlier this year for a pretty good deal. Only thing is the guy said they were 13:1! They didn't seem like they were that high but no matter what I knew they weren't 9:1 so I bought them with the intention of clipping the domes. My buddy made the piston holding fixture in his CNC mill and it repeated within .002". With a 2.065" compression height and the block decked about .010" to square it up I ended up cutting off the .136" high dome to get flat tops with zero deck. 915's and a thick gasket I should be at 9.6:1.
For some reason I couldn't up load pictures here so I just put them on this -

I don't know what changed but I never had an issue with pictures until now.
