When I spoke to them today they said if I sent them back they would sink the valves.I was told that will mess up the flow and I already waited almost 2 months to get these heads so I don't want to do that.

I was told that sinking the valves effects the way the head flows.I don't think you will notice that or the lower compression.How much clearance do you have cause if you are hitting the piston I don't think .040 is enough.
