John,that was for this set.That is the great thing about these.Custom options at no cost.Yes ,right now I am focusing on an iron head 9.5-1 closed chamber set up.There are available wo /notches.I also reread some of the sae papers on quench..040 is the absolute minimum recommended and even .080 is beneficial.Price wise I think it is very fair.Sealed power forged pistons and a notch job would cost more.As far as hyper stuff,I do not use them ,I would rather run the old stock cast stuff.

Thanks for your input,Mike
