I recently changed both cylinders heads and gaskets on my 1998 ZJ 5.9L because there was an high pressure issue on cooling system and the chemical test revealed C02 gas presence on cooling fluid.
Before then, I did not notice any white smoke from exhaust tail pipe but after installing new heads, white smoke comes out from it.
I did a double check of all new head bolts. In particular, I noticed that it was very difficult to tighten the bolts near the body because there is a very small space to introduce the torque wrench.
In my opinion, the head gaskets that I used, were not appropiate for ZJ cast iron engine.
Is there a specific model of head gaskets for ZJ engine?
Would it be better a Victor Reinz old design 6111061400 or a Fel Pro 519 SD?
What do you think about?
Thaks for helping me!

My head gasket choice for a stock(ish) 5.2 or 5.9 Magnum would be Felpro 1008. edit: 1008 is .039" compressed, 519SD is .050". I see no reason to go with the thicker one. Make sure engine block deck and heads are straight, should have no issues with the 1008.
