Question for engine experts

JFP, do you have insight regarding 3.2 & 3.4 heads?
I've sent an oil sample to Blackstone for analysis... we'll see what they have to say.
I found the oil in coolant (just a bit of Choco on the top of the coolant in the reservoir) as I inspected a couple of days after making a 400 mile trip from VA to SC. I was running Dash Command for the duration of the trip, just watching data. As I got into traffic, coolant temps climbed from a highway temp of around 180 to a max of 223. I noticed that I could smell coolant. I turned on the AC to get the fans going, and that bought temps down to around 210.
It'd be nice if it's just the heat exchanger, but I'm still guessing heads. If the bottom end is still good and the 3.2 heads will work, then the 996 gets a salvage motor and the 986 gets a hot rodded 3.4. And I'll be functionally broke for a good while.
