Holy Crap,I spent my hard earned $$$ buying not just 1 set but 2 sets of 572-13 heads,when I could have save $$$ by using 440-1 heads  I just let 1 set go with my spare engine,but you can bet the farm on this I won't be replacing them with a set of 440-1 heads. 
I would run another set of -13's anyday, It's not all about flow numbers. 
 that is so true. the 572-13,s have alot more port volume than the -1,s, at the same flow.....
