The 240s are not too big. Theyre made for a hi po 440.
Yes, you could go too big. Heads like Brodix or Predators would be too big.
Go with the 240s....
Just to make sure im getting this right: so 240 instead of 210 wont negatively affect daily driving?
210 is barely above or at stock and in my mind 240 and cubes is totally doable and my "weekly" driver runs a 470 stroker with 276-281 @ .050 12.1.1comp but I'm 3050 lbs roughly, run an 8" 5200+ vert and 4.10's so no problem............
