Help diagnosing possible head gasket?

Hi guys. I have not ceased to learn from this forum and am asking for input on a possible head gasket job. The car is a 1985/2 944 NA A/T. I bought the car from a guy who had it less than 30 days and sold it to me telling me that the head gasket is blown. Said it was overheating and milky oil. I want nothing else to do with him so have only that much info. He removed the DME/ECU before I picked it up or I didn't notice it was not installed - towed it home.
Anyways, I have this information:
There was a little moisture on the dipstick and no oil in the engine when I first looked at it.
I put oil in and it started up right away and whined pretty significantly until I topped off the coolant. I saw no white smoke and the exhaust seems normal; not sweet.
Normal oil pressure - 5 bars at start, 2 bars at operating temp.
Did compression test - 1:145psi, 2:152psi, 3:148psi, 4:150 psi
Did leakdown test - 1:18%, 2:18%, 3:9%, 4:14%
I haven't driven it except to take it around the block, so have no significant mileage on the engine to see if the coolant is decreasing significantly. I have a friend who says "Just do it!" to the head gasket job. Trying to decide if I should just take the plunge.
