Gasket brand selection for head gasket reseal 03 XC70

[P2metoo]

I have exhaust gas getting into my coolant and symptoms of a blown head. I read that I should go with the Volvo brand for the head gasket but what about all the other seals? On IPD and FCP Euro I see kits from Victor Reinz, Elring and Mahle. Any recommendations? It's a lot of work to cheap out on seals. But if all are the same, I will go for the lower price.
Any other tips or links are welcome.
Thank you.

Here's my mantra on head work parts
> Must be Volvo: head gasket, valve stem seals, spark plug tube seals
> Go with Corteco: cam seals
> Victor Reinz: most other seals and gaskets

Here's most of what I bought for the 07 XC70 head work, including cooling hoses and timing parts, (NOT guaranteed to be a complete list!!):
NOTE, CTO = Corteco branded
NOTE, VOL = Volvo branded
REI = Victor Reinz branded
ELR = Elring branded
