HR vs VQHR heads?

Just a real quick question...the HR upper mani is different than the VQHR mani cause the lowers different. But is the lower to head different? Like if you wanted to run a HR mani instead of buying the M370 you buy a HR upper and lower mani and bolt it to the VQHR heads?

IIRC the bolt hole locations are different

Isn't it the VQ37/VHR?

If so, call Clark at JWT - he built the engines for the 370Z's running in Grand Am GS and will know the answer.
