To Stroke, or not to Stroke

Well said 68383GTS, that pretty much says it all! I am going to start out with a 451-stock heads but bigger valves. I plan on adding on later considering it seems the way to go. Probly stealth heads, MSD ignition and maybe a pro-charger eventually but I understand you have to build the engine for a pro-charger.
I will be taking the blk in to get them started on it next wednesday, time for pistons. What is a good 451 stroker piston, I know 440sourse has some good ones for $550, is there any other available for less money?
