Head Gasket replacement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Dova · 06-12-2009, 06:23 PM

So I am changing out my head gasket that blew and i am trying to pull off my heads. I am on the passenger side head. I've removed the intake manifold. All the push rods and the 7 nuts holding it on the inside and i believe it's 8 nuts holding it down on the inside. What else do i need to do? I am new to this. I have read an article about it i'm sure i'm missing one or two small things preventing me from getting it off. Any help would be greatly appreciated. It's on a 72 350 the engine is supercharged if that matters much

Here's a previous thread that may help you...

Remove all of the bolts and here is a pic of the torque sequence if you need it.

Thanks i've read that thread and didn't know the exact torque sequence i was going to do something similar to that. The heads still don't want to come out taking those bolts out. Is it just a suction that i have to get past?

Stick a pry bar down into a port or water passage and lever it off. The head gaskets get real stuck after awhile. An 18 inch bar will pop it right off.

If you're sure you have taken all of those 17 bolts out then you may have to pry it off. I use a pry bar to loosen it up. Find a lip on the head and stick a large screwdriver and see if you can break it loose. After many years it gets stuck real good sometimes.
