Heads replacement 2.9

Afterbuying a 1989 Ford ranger fixing all the electrical glitches, and then I noticed I was having to replace antifreeze very often and smelled it while I drove it. Replaced the heater core and hoses, radiator, and hoses new thermostat and it still putting antifreeze somewhere. I come to the conclusion I got a bad head gasket or a cracked head. Reading the forums Iíve noted the heads are prone to crack. So my question is has anyone out there in ranger land know of any aftermarket heads that are bolt on to the 2.9 block. I donít want to pull engine unless I have to. Engine compression is good on all six. I will replace timing Chan and gears while I got it torn down. Any help will be appreciated.

Do the Glove test before assuming it is a cylinder leak, 100% accurate



The Glove test
Get a Latex Glove and rubber band
COLD ENGINE
Remove Radiator cap
Remove overflow hose, plug this opening, gum putty, ??
Put latex glove over Rad cap opening and seal it in place with rubber band
Unplug Coil spark wire, you want a no start

Crank engine over and WATCH the glove
It should just lay there, not move at all
If it starts to bounce then you have a cylinder leak

If it bounces then remove one spark plug at a time and crank the engine
When glove stops bouncing the last spark plug removed was from the cylinder with the leak
Put spark plug back in to confirm

You can have more than one leaking cylinder, you will see glove bouncing less when spark plug is removed from one leak, make a mental note and keep going to remove next spark plug.

If glove just lays there the whole time then we will have to move on to other causes of the white smoke.
The Glove test is definitive and free so good to do even if you KNOW head gasket is not the issue
