Oil in my radiator and a few questions

[Tugmaster]

First of all I am a complete neophyte when it comes to Model A's. I've worked on and restored a few cars over the years but this is my first A.
I bought the car from a gentlemen who bought it from the estate of the previous owners widow.It sat for 10 years from his passing until now. "Supposedly" the motor and trans were completely rebuilt. It ran ok when I went to look at it. When I got it home I decided to do a little investigating of my own and pulled the side cover. I was clean enough to eat off of!! I drained and changed the oil which came out very clean. I drained the old antifreeze and put in water. The anti freeze looked good with just a little rusty tint but not bad.
I started it today to tinker with it some more. When I pulled the rad cap I noticed a bunch of emulsified oil swirling at the top of the radiator. I pulled the dip stick and the oil seemed fine. There was also a little weeping on the d/s between the head and the block. I was going to do a compression check but at this point I think I should just pull the head and look at the cylinders and head.
My questions: Am I on the right thought path here? I don't want to chase my tail so to speak and want to do it once and do it correct. Who makes the best head gadget for a stock head? What is the best way to pull the head. I read somewhere that you can loosen the head bolts 1/8" and start it up and the head would pop loose.
Thanks in advance for any insight you can offer.
