So now you are saying 360 heads are tiny?, all I know is you make my head hurt. Stay on topic man, is it a 302 or a 587 that you make love too?, and I can tell you the 587 is the best flowing stock small block head casting to work with, I have used several sets. So the guy has a 410 with 587 heads and a .590 racer brown cam, far cry from a 318 with 302 heads. Its pretty obvious you like to sit back and watch the mayhem after you stir the pot, and repeat, and repeat, well have fun man.
