They are cast iron??
After getting low compression on two adjacent cylinders I decided to pull the heads off the engine. It would have been nice to do a leak down after the compression test but I wanted to pull my heads off anyway.
Everything went smoothly, I have a growing grocery list with noisy pulleys, a missing injector diffuser cap, pitted rocket arms. My intake manifold heater core pipe is quite corroded, does anyone know whether it's pressed in, worth changing?
After pulling the heads off which I found rather heavy, put a magnet to them, they are cast iron?
Two of the exhaust manifold bolts were stripped?? And I found no gasket between the heads and the manifolds?
Also, do the manifolds require a round gasket to lead pipes? There was none.
Someone must have had those heads off before...
The passenger firewall piston was pretty clean and shiny, suspecting a water leak. The middle one with the gas-fouled plug had quite some carbon build-up.
On the heads, the two middle cylinder exhaust valves were seating much lower than all others. I pulled one of them out. It had quite a bit of play. Also the valve itself was pitted. I thought it was weird that they sat so low.
Since I have iron heads, should I get them rebuilt or go with a new set of 93tm's from Alabama Heads?
My coolant, the inside of the exhaust manifolds, the inside of the intake chamber, the valves, were all quite rusty. My oil was clean.
It's been a pretty easy job so far, a little time consuming. I've been working on it for a total of 6 hours I believe. Now onto cleaning up surfaces and ordering my list of parts. Should run like a champ afterwards!
