Coolant in oil... OK so I just had me engine rebuilt to a 355 and today i just notice milky oil when i open the oil cap. So i pulled the covers off and its all under the covers.. Did a compression test
CYLINDER
1- 260psi 2- 230psi
3- 220psi 4-235psi
5- 260psi 6-230psi
7- 220psi 8-240psi
so does it look like i just need to change the drivers side head gasket?
any suggestion on what to do? should i replace both or could i just replace the one? The engine has no miles on it and the car has just been started a few times...

head gasket....it happens. when i did my first cam, my new head gaskets lasted 1800 miles. Once you have the head off just make sure you check over anything possable that would make it leak.

I'd suggest that while you have the heads off, you have a machine shop clean and rebuild them. For non-performance rebuilds, the cost is pretty reasonable. They will automaticly check them for flatness. It's a lot of work to get the heads off in this car and would be kinda foolish to not have them at least gone through.
Your best investment here would be a set of ARP head bolts or studs.
Don't forget, for threaded fasteners that go into coolant, you want a really good sticky gasket sealing goop, not any type of thread lube with Teflon or moly that will wash away with heat and use.

The heads were milled before install. and im using arp head bolts...i used permatex for thread sealant and the arp moly lube.
