AFR 225cc vs Dart 250cc heads I have a 402 short block with callies crank/rods and -2cc Diamond pistons. I need some advise on which heads to use. I currently have both AFR 225cc and Dart Pro 1 250cc heads. They both have 2.08in/1.60ex valves with PAC 1521 springs. The motor will be setup with a large direct port of nitrous. I just need some help choosing the correct heads for this setup. Thanks in advance.

I am betting most people will say AFR hands down.

With nitrous bigger the CC runner the better.
If it were N/A I would go with the AFR's as they are renowned for their mid lift and low lift numbers which will really help propel a N/A car.
With nitrous while low and mid lift is still important it isn't as big of a "break the deal" type thing.
The Dart 250's is what I would use.
