Anybody have any experience with h-11 head studs by A1 technologies?

Looking for a more affordable head stud than the arp 625 studs. The h11 seems to be the I between as far as strength and cost goes. I'm going for around 900-1000 hp on my future build. They will be ran with an O-ringed head if at helps. If any one has any experience with these studs please chime in
