Hey - that looks like a pretty good find, but I’m just going to sit tight and live or die with what I have. Probably keep the cost under $200.
Well, AutoZone is saying the two heads are interchangeable. Could’ve sworn there was that extra bracket bolt hole in the firewall-side head. Need to check those notes I took to prove them wrong. Also - realized later that I never took the spark plugs out of either head, and I had Sharpie’d numbers on each plug, so I should be able to put them back in their original places.
I’ll probably go ahead and check the lifter faces. All that’s in the way is just a flimsy sheet-metal retaining bracket over the tops of them. I know they need to go back in their original locations, but is the orientation critical, too, or will they only drop in one way?
Regarding the honing - still not sure if I’ll do it. Part of me says, “Go ahead … no guts, no glory … you’ve got everything apart right now … this isn’t your primary vehicle … the extra parts aren’t going to cost much … and this is as much about the experience as anything”. The other part of me says, "who’s kidding who? … you’ve barely had enough time and energy to get as far as you have to this point … and you want to EXTEND this project??? Just get those new gaskets and seals installed, throw in the new T-Stat, and “drive on”! Can’t decide …
As for the heads, I DID clean them up and the only thing I noticed was a pinhole in one of the freeze plugs (even though they all LOOK clean, shiny, and new). So probably need to replace all four plugs, right?
sloepoke, db4690: It’s the Vulcan. Sorry, but I thought all 3.0L’s were Vulcans, no?
Funny you mention these cast iron heads are “robust” and “not prone to cracking”. That’s what I thought, but I called two machine shops and they BOTH said the same thing: “believe me, they’re cracked … they all crack … blah, blah, blah”. Made we wonder about the veracity of these places.
I have to admit, your advice makes the most sense to me: just throw it back together and “drive on”. Even so, I’ll need to at least get those valve seals, and now new freeze plugs, installed. Never done either of those before. Another project within a project. That’s the problem with me: everything is always the first time, so it takes me forever …
