Think a bit first. How is the bottom end? Bores and bearings.
And, the transmission? Planning other stuff with the head removed?
complete head job, including a skim? The cause of the busted gasket, found and a fix planned. You think some or all of the studs are corroded and may well bust on cracking the nuts?? Rust and Barr's leak plugging up the radiator and coolant passages in the engine?
Renew the freeze plugs...
Once past that stage, plan the work. Or.....

If you look carefully at the top of the block in the photos on #7, you'll see slots between some of the bores. If you're engine has these, then you're better off, because this eliminated the cracking between the bores suffered by earlier engines (like I had !!). For these slotted block engines head gasket replacement is a simple job. For the previous long-stud blocks, there was almost certainly cracking between bores that meant just replacing the head gasket was a waste of time and lipped liners needed inserting, hence a full overhaul of the engine was the best option. A lot of US guys then just junked the engine, and lumped the car with a super-reliable US-made V8.

Head removal
Well some good news , I went out to recheck the compression and found that the gauge was not working properly. The little catch that hold the PSI until you read and then press to release PSi was not working. I had checked cylinders 6,5,4,3,2,1. so 1 & 2 were checked last and that is when the little switch went out. back to the slots between he cylinders are they visible with nothing removed from the engine. Thanks Jerry

You may find this thread informative, although not too serious.
