Are valve reliefs for ls7 heads much different location to ls1/2 heads?

I'm wondering if I rebuild one of my ls1 short motors with forged pistons that already come with valve reliefs, will my small bore ls7 heads have p/v clearance? If anyone knows for sure I greatly appreciate it. Because if not I think I will just valve relief my stock ls1 pistons instead, which I'm not really looking forward to doing as it means i'll have to disassemble my ls7 heads and use them as guides and buy the cutting tool to do the valve reliefs. It's much easier to just buy pistons.

The valve reliefs are definately different between the two. LS7 reliefs, the valve pocket is pushed over against the cylinder wall.

Thanks. I know the valves are moved slightly, just not sure by how much. I guess i'll find out when I clay one piston.
