a 2315 piston and 440 source head are the easiest way to do this. custom pistons/pins with a quench dome may be $1000. I know arias has made this type of piston for 440's so they should know what to do. considering the cost of head refurbishing and new custom pistons i think the 2315 pistons and source heads are an easier alternative and might be cheaper; plus this has a good quench distance. if I was building a 383 this is the combo i'd look at first.
