Removing 74 BB heads ??

I know about INSTALLING heads....but....is there a correct bolt sequence or technique to follow when REMOVING heads that have been installed for 33 years ??

Thanks....I'd rather ask a dumb question than wish I had !

You'll gain a new appreciation for aluminum BB heads once you lift that "Detroit Wonder Metal".

The intake isn't a whole lot better.

Now just think, If I had AL heads, intake, water pump, how much weight could be removed off that front axle.

Don't they make AL blocks too!!! Ya, Ya, that's it. Aluminum block it is.

Just my fantasy.

Thanks for the info...

Would you believe this all started as "just a good engine clean up!"

I know that feeling. What ever it is that I am doing, the 30 minute job turns into a 3 week project.

Are you replacing the heads with an aftermarket version? What about rockers, valve springs, etc.

What are your thoughts on original exhaust manifolds vs. headers?

Are you considering any head work - like a pocket port? Valve job/seals?

And, please keep us posted on your engine work.

Yup, that 80 lbs. of cast iron generally tends to pick your feet up off the floor when you try to lift it up while leaning over the fenders.

Be very careful on the passenger side if you have A/C. Tolerances are mighty tight there. I managed to punch a hole through the blower housing when I broke the head loose. All that weight tends to go where it wants to.

on my 71, the heads wouldn't come off. I had to run a chain through them and use a cherry picker to "break" them loose. Its like they are glued to the block.
