It should be fine. I run a stock bottom end on the TT440. It's got the cheapie Speed Pro forged pistons from Summit. The bottom end survived way too much detonation while I was learning to tune it with 8 psi. I ran 15 to 17 psi for a while and even surged it to 22 psi by accident.
The detonation transferred metal from the piston crowns to the cylinder walls and blew the head gasket. There has never been a problem with the rods and crank. The bearings weren't hurt too bad either.
