How to remove a stuck Cylinder Head from an inline 6

I removed all the bolts from the head but it wont budge. I didnt want to pry it off since it could damage the surface area so Ive sprayed PB Blaster around the perimeter and Im waiting for another go at it.

Any tips?

This will probably sound stupid and please don' take it wrong, but is there any chance you missed removing one head bolt? My budy in high school missed one bolt and was trying a large crow bar on the head. Our teacher wents nuts on him. It's stuck with me for 30 years.

Do you have 14 bolts on the floor?

I have had to take a jack handle (Floor jack) stuck it in one of the ports.
And remove ine that was stuck on a old C50 Chevy Bus.
What a pain in the "A" And when it came loose I about took my face off with the handle!

Put the spark plugs in it but leave the plug wires off and spin it over with the starter. It should pop it loose.

Success!

took the end of a hammer that had a rubber grip and put that in the 1st exhaust port and pry'd it off.

When I removed it some engine coolant had overspilled into the 1st cylinder

I absorbed what was sitting there with paper towels. Hope that doesnt mess up the works.

heres a pic of the engine

Yeah, sanded primed and painted all of what is now black last weekend. Actually forgot to remove some masking tape on the top of the towers

Hoping to spruce up and where needed-replace the rusted parts, like the fuel and water pump.

Taking in the head tomorrow to have it redone.
In the meantime Im planning this weekend while the weathers nice to paint some of the removed parts like brackets, power steering pump, fan, AC bracket and even would like to start painting some chevy orange on the motor, valve cover, thermostat, manifolds...

Really nice work there! You give me hope.

Ill have to do it the less than perfect way, and leave the engine base in.
No cherry picker and stand for me, no room

As long as I leave it better than when I got it Ill be happy.

What size engine you have Jimbo? The reason I ask is because if it's a early model six, the the seperate intake/exhaust manifolds and not the (newer 250 with the integral head) and it's a 230 or 250 you might want to look for a cylinder head for a 194 and have that redone. The 194 had smaller combustion chambers and will give you slightly higher compression.

Thanks. I was originally just going to spruce mine up a little with the engine in the car but the more I looked at it the better I felt it would come out with the engine out of the car. I was lucky enough to have a friend with a cherry picker and engine stand and parents with a huge barn (who were out of town so I could make a big mess without their knowledge!)
