p8r head on my ls

Hey, I'm putting a p8r head (jdm b20 head) on my b18b in little while and I was just making sure that i can use a ls timing belt and ls intake manifold. Also will my header work too? Thanks, Zach

Why are you doing that? You won't see a difference really at all? If anything less because of the restrictive Intake Manifold

Everything will work fine...but there's really no point in the swap.

just for reference sake: the head is slightly better flowing on the intake side (33mm ports vs 31mm)

i'm pretty sure the head just bolts up.

It also has 84mm combustion chambers which is good for a 2 liter...but no real point in putting it on an LS.

Would it be better than an LS head w/ a B20z swap or with this head? Both w/ the B20z

The P8R head won't fit correctly without either welding up the 84mm combustion chamber to fit the 81mm bore or sleeving the block to 84mm. The P8R head is a nice head though because it flows about as well as a PR4 head, so good luck trying to get it on there.
