AFR 227 and SRP piston to valve clearance

Hey guys, im thinkin about getting a set of the AFR 227 heads for my 406 but am worried about the 60/40 split valves and piston to valve clearance. I guess my question is, do you have to run a special piston to run this type head? Since the valve is rotated slightly i wonder if the valve releif in the piston will have enough clearance with my current piston? I have the standard SRP line of pistons with -5cc reliefs. I always check p/v clearance with assembly but i dont want to shell out 2 grand for heads that wont work for my setup and have to spend another 600 or so for another set of pistons. This is already a running engine but i want to upgrade my Motown 220's. Thanks
