7.425 if you want the valves to stay open. Another case of miss information. 7.4 is a longer than stock pushrod for the smaller base circle of aftermarket cams.
The TR224 is probably the most common cam out there. 7.4 is what you need. Once you mill heads, checking pushrod length is necessary.
I ran 7.4's with stock heads, and I run 7.35's with my AFR 205's milled 0.030 and a stock GM gasket. I did check the pushrod length and valve lash. (actually Slowhawk did
with me)

i have the 7.425's in with that cam and TSP 5.3L heads. i asked patrick and a few others and they recommended what i have. either should work fine. tsp said they use 7.4's with that setup.
