Guys, I have removed 10 bolts from each of my heads, 5 beneath the valve covers and 5 closer to the exhaust manifolds. At this point I expected to be able to lift off the heads. I am exerting enough force that I am moving the block (ie. nearly picking it up). Am I missing something? Or is this typical with gaskets and alignment pins. How do I proceed? Appreciate any help. Steve
How are you attempting to remove the heads?? What technique are you using?? o No: Usually, a large screwdriver or prybar placed in an intake port (or exhaust port), and using a fairly minimum amount of force, is enough to free the head from the block. uzzled: More info and/or pictures could be useful. :TU:
There's a lot of surface area on the 455 heads, a lot more than your typical 4 banger. I find it takes me a lot more umph to budge the 30+ years of frozen 455 sealing than it does for some of the smaller/newer cars I've worked on.
Thanks ALL! Guys, I read your replies at 6:58pm and went out to the garage. I was back inside with hands washed and heads off by 7:20pm. I appreciate the help. Took me until now to reply because, it being my first 455, I was a little emotional. The big beautiful valves, the 4.315" bores.....You guys understand. Anyway I am quitting for tonight. Tomorrow I am moving on. Thanks Again.
Thats a good idea! :TU: Never tried a section of an old broom handle. :bglasses: Good luck, Steve. Keep us posted. Feel free to ask questions. The more specific the better.
