Ok it's tax return time and i have some extra $$ to play with.... I am interested in buying a pretty decent set of streetable bbc cylinder heads. My talldeck 427 is basically stock right now so i don't need anything to crazy....which brings me to my next question. This is my daily driven truck and i don't have time to pull it down right now. Would anyone possibly know what the measurement and type (flat top, dish, etc..) pistons i prolly have so i can look into getting some ???
