Replacing Head Gaskets

[69C10@16]

Ok, my engine has been running more than extremely crappy lately. Could NOT figure out why. It had a "puff rattle" when the engine was under load and when it got to about 1800 RPM it "suddenly" gained some power. Tried a timing light out and Number 1 wasn't firing at normal intervals. It was sperratic. Walked the timing light around the engine and pistons 4 and 8 did the same. Firing order: 18436572. 1, 8, and 4. Huh, replace dist. cap. Same crap. Started inspecting the "puff rattle" with some compression testing. 4 and 6 have ZERO compression. Put a plug back in 6 and compression tested 4 and got a little compression. So i'm guessing the head gasket is blown between 4 and 6. Valve springs are good. And if it was the valves then putting a plug back in 6 wouldnt have given me compression on number 4. The puff is clearly coming through the carb so when 4 is on its exhaust stroke the intake valve for 6 must be open causing the noise. I figure I'll replace the head gaskets to get my compression back and then inspect my ignition issues. Just wanted to make sure I was on the right track.

Heres the list of stuff I know I need, add to it if I've missed anything please.
